66 inches 23 inches cobas z 480 analyzer Real-Time PCR Based on LightCycler® technology 96 well plate format 4 channel detection The cobas 4800 system is comprised of two instruments. The cobas x 480 instrument for automated specimen preparation and PCR set up and the cobas x 480 analyzer is a real-time PCR system for amplification and detection based on LightCycler® technology. These instruments are linked via the cobas 4800 system software. The Roche Diagnostics cobas 4800 software runs on a dedicated control unit. A handheld barcode scanner is connected to the control unit. It is used to scan reagent and reagent reservoir barcodes during loading of reagents, as well as sample barcodes to setup the work order file. cobas x 480 instrument Testing from primary and secondary specimen tube Specimen barcodes automatically read by system for positive specimen ID Batches of 24 or 96 © 2014 Roche

4 HPV/HPV Genotype tests, CT/NG, and oncology markers & others on the same system
cobas 4800 v1.1 cobas 4800 v2.0 cobas 4800 v2.11 HPV CT / NG BRAF EGFR EGFR RUO* PI3K RUO* KRAS RUO* HPV, CT/NG, HSV1 BRAF, EGFR, PI3K1, KRAS1 MRSA1/MSSA1, Cdiff1 The cobas CT/NG v2.0 test helps optimize profitability by enabling your lab to run multiple tests on the same system. (Review the tests listed above, pointing out that some are RUO and some are not yet available in the U.S.) One system…many tests…which means your lab won’t need to make capital investments in multiple instruments, which is always good for the bottom line. * For Research Use Only.

Tip Carrier The tip carrier holds 5 trays of 96 tips each. Sample Loading Area The sample loading area can hold up to 94 swab and urine tubes, 94 Sarstedt tubes, and 94 PreservCyt® (ThinPrep) vials. Note: the PreservCyt vial feature will not be available at launch. Stationary Carrier The stationary carrier is where the specimen preparation takes place and the processed specimen is added to the master mix, for the real-time PCR amplification and detection phase. Reagent Loading Area Reagent are transferred to reagent reservoirs and placed on the system. © 2014 Roche 5

6 cobas® 4800 System Requires Minimal Maintenance
Daily Maintenance Once every 24 hrs. Requires 2 – 7 min. of operator time No Bleaching of system components Weekly Maintenance Includes daily maintenance Operator should wipe down carriers with water No Monthly Maintenance Preventive Maintenance Status Performed bi-annually by Roche Field Service The cobas 4800 system software provides a graphical interface for the operator. The software features a wizard that will guide the operator through the tasks that need to be performed. This is the system overview screen of the cobas 4800 system software. System and maintenance status at a glance, changes in color will also indicate status. If maintenance is required, the system will not operate. © 2014 Roche

7 cobas x 480 Instrument Positive patient ID
Sample Carriers Specimen loading area holds up to 94 specimens 24 sample carriers & 12 sample carrier can be combined for a total of 94 samples on board for the cobas HPV test Specimen bar-codes are read by the on board barcode reader as the specimen carrier is loaded. The software links the specimen to the order providing positive specimen identification through out the testing process. 24 sample carrier holds up to 24 PCR Media tubes or 24 Sarstedt tubes The specimen loading area holds up to 94 patient samples. Controls are loaded on the specific reagent rack, which will be covered shortly. As the specimens are loaded onto the system, the onboard barcode scanner reads the barcode and the specimen is connected to the pending test order. There is no need to load specimens in a specific order. The cobas 4800 system software uses host query to match specimens with orders that have been downloaded from the LIS or from the Work Order Editor program. This linkage between the specimen and the order also provides positive specimen identification throughout the testing process. 12 sample carrier holds up to 12 PreservCyt vials © 2014 Roche

8 cobas x 480 Instrument Load Samples and Work Order File
Uncap samples. Place samples on corresponding carrier. Insert sample carriers on autoload tray. Click Load Samples. The first step in beginning a run is to load the specimens. The operator must first down load orders from the LIS or prepare orders with the work order editor. The intuitive cobas 4800 system software will walk the operator thru the process of loading the specimen carriers. As the racks are loaded into the deck the barcode reader will match the specimen number to the work order number providing positive patient identification. Specimens do not need to be loaded in any particular order. © 2014 Roche

9 cobas x 480 Instrument Designed for reliability
Benefit CO-RE tip technology Reduces aerosol production upon tip ejection Improved system reliability Air Displacement Pipetting with total aspirate and dispense monitoring (TADM) Verifies sample transfer with digital audit trail Liquid class optimization for all reagents and sample types Detects pipetting errors during the aspiration step in real time Anti-droplet control Reduces droplet production from evaporative expansion in the tip Reduces a source of contamination Dynamic Positioning System Flexible, precise tip positioning Adapts to any specimen container Pipetting is a very important part of the preparation step, and the system employed on the cobas x 480 instrument is a highly innovative one that contributes significantly to the overall reliability of the cobas 4800 system. The cobas x 480 instrument uses an air displacement pipetting system built on the Hamilton liquid handling systems, which are known for their reliability in fluid handling. Roche has used Hamilton systems for over 10 years in the blood screening arena. As you can see these features not only contribute to the overall reliability, the design of these features plays a large role in the reduced risk for contamination. Lets take a closer look at CO-RE tip technology. © 2014 Roche

10 CO-RE Tip Technology Compression-Induced O-Ring Expansion
Secure, air-tight tip seal Gentle release to reduce aerosol formation Reduced mechanical strain for reliability Tips locked in place by an O-ring that fits into a groove inside the neck of the tip Piston Compression Induced O-Ring Expansion, or CO-RE tip technology locks the pipette tips in place with an o-ring that expands to fit a specifically designed groove in the neck of the tips to improve sealing. When the tip is released the o-ring is disengaged resulting in a gentle release of the tip which reduces aerosol formation. In addition, this system enables tips to be connected without mechanical force, which over time improves the reliability of the system. O-ring O-ring in groove Tip O-ring groove © 2014 Roche

11 cobas x 480 Instrument Aspiration and Dispense Monitoring
The air displacement pipetting comes with total aspirate and dispense monitoring (TADM), a software application that performs sample tracking to verify the sample transfer with a digital audit trail, by measuring the pressure responses for each pipetting step and comparing them to the expected pressure response curve. This verifies that proper sample volumes are transferred and reagents are added according to the protocol selected. TADM detects pipetting errors during the aspiration step in real time, and uses liquid class optimization for all reagents and sample types to differentiate the viscosity of the different liquids used in the system. The cobas x 480 instrument also provides anti-droplet control by reducing droplet production from evaporative expansion of the tip. This is an important feature that reduces a potential source of contamination. © 2014 Roche

12 cobas x 480 Instrument Instrument Deck Overview
Reagent Carriers Assay Specific Reagents The reagent carriers hold specific and generic reagents for batches of 24 or 96 tests. The 50 mL. and 200 mL. reservoirs will hold the generic reagents used for all assays. No reagent preparation is required with the cobas 4800 system. Assay-specific reagents such as master mix, magnesium and controls are ready-to-use and provided in barcoded vials that can be placed directly on the system.  Scan-Scan-Pour-Place Principle To minimize handling errors the reagent reservoirs are filled and placed using the scan-scan-pour-place principle. First the operator scans the barcode of the required reagent using the handheld barcode scanner. Then, the operator scans the barcode of an unused reagent reservoir, using the handheld barcode scanner again. The reagent is poured into the scanned reagent reservoir, and the filled and scanned reagent reservoir is placed onto the required position of the reagent reservoir carrier as indicated in the cobas 4800 system software wizard. 50 ml Reagent Reservoir 200 ml Reagent Reservoir © 2014 Roche

13 cobas x 480 Instrument Stationary Carrier
Heater / Shaker Magnetic Plate Home position for DWP Loading position for PCR Plate The stationary carrier is the area where the samples are processed. It is mounted on the instrument deck and is not removable. The stationary carrier holds four units: the heater/shaker unit, the magnetic plate, the deepwell plate holder, and the AD plate holder. The procedure for sample preparation includes: 1) media-specific processing, 2) generic binding, washing, and elution, and 3) working master mix preparation and PCR setup. The deepwell plate and AD plate are moved from the plate carrier to the stationary carrier while isolation takes place. © 2014 Roche

14 cobas x 480 Instrument Sample Preparation on the stationary carrier
Lyse Bind Wash Elute Heater / Shaker Lyse Bind to Magnetic glass particle Magnetic Plate Wash steps Extraction (deep well plate) holder Sample and reagent addition The deepwell plate and AD plate are moved from the plate carrier to the stationary carrier while isolation takes place. The appropriate reagents, samples and controls are pipetted into wells in the deepwell plate. The deepwell plate is moved to the heater/shaker unit where the sample is lysed and nucleic acids released. The Magnetic Glass Particle reagent is added, and the nucleic acids bind to the particles. The deepwell plate is then moved to the magnetic plate for two washing steps. The magnets in the magnetic plate hold the magnetic glass particles in place so that the nucleic acids are not washed away. After washing, the elution buffer reagent is added which causes the nucleic acids to be released from the particles. Following sample processing the master mix and processed specimen are added to the AD plate. Once complete, the deepwell plate with residual processed specimen and the AD plate with processed specimen and master mix are returned to the plate carrier. AD Plate holder Extracted specimen + Master Mix © 2014 Roche 14

15 When sample preparation is complete the system instructs the operator to remove the completed AD plate, seal the plate and transfer it to the cobas z 480 analyzer. The barcode on the side of the AD plate assures that positive ID is maintained when the plate is loaded into the cobas z 480 analyzer. The cobas z 480 analyzer performs real-time PCR amplification and detection, using LightCyler® technology for detection. Simultaneous detection on five detection channels allows analysis of signals from multiple dyes in multiplex real-time PCR assays. As a benefit of this, multiple results can be reported from a single reaction. cobas z 480 Analyzer © 2014 Roche

Following sample preparation the AD plate is sealed and moved to the cobas z 480 analyzer The sealed plate is placed on the loader and the Real-time PCR begins when the load button is pressed and the plate is pulled into the cobas z 480 analyzer Positive specimen ID is maintained via the bar-coded microwell plate When sample preparation is complete the system instructs the operator to remove the completed AD plate, seal the plate and transfer it to the cobas z 480 analyzer. The barcode on the side of the AD plate assures that positive ID is maintained when the plate is loaded into the cobas z 480 analyzer. © 2014 Roche

Design Benefit Unique fluid filled Therma-Based layer in the block provides uniform heating and cooling across the entire plate Shortened cycle times Improved temperature homogeneity Improved accuracy The thermal block on the cobas z 480 analyzer is designed with a unique fluid filled therma-based layer. This provides the ability to have shorter cycle times, and improved temperature homogeneity from well to well resulting in improved assay accuracy. © 2014 Roche 17

18 cobas z 480 analyzer High Performance Real-Time PCR
Design Benefit Single step processing with few moving parts More reliable More reproducible High performance optical system with 5 optical channels Multiple target detection from a single reaction tube Accurate data capture across the entire plate The cobas z 480 Analyzer has been designed with very few moving parts which contributes to the reliability of the system. There are 5 optical channels used to measure multiple targets in one reaction. Advanced Digital Optics Design © 2014 Roche

19 Multivariable Algorithm Eliminate the guessing game
Instrument-level processing corrects for optical system variability Filter design and manufacturing process minimized spectral cross-talk Primary data reduction algorithm is fluorescence scale invariant No more simplistic threshold methods for Ct calculations Instrument-level processing – Each cobas z 480 analyzer is uniquely calibrated to account for system to system variability. The filter wavelength were optimized to minimize spectral crosstalk between the different filters. Scale invariant simply means that the algorithm is not dependent on big an optical signal is achieved - it's based on relative fluorescence increase and not some absolute signal increase. Ct calculations are not based on a simple crossing of a threshold value (which can be very arbitrary).  Other methods use simple algorithms such as second derivative peaks to call a Ct value. With other systems, a technician is required to view curves of ambiguous results. The multivariable algorithm used in the cobas 4800 system accounts for a variety of signal artifacts such as late peaks, double humps and slow growth rates to produce results that are positive or negative with no grey zone.

20 Expanding System Capabilities User Defined Workflow software
Design Benefit Dual boot setup with a partitioned hard drive and separate database Based on the LightCycler® 480 Software v.1.5 Full functionality of the current LightCycler® software Allows user defined assay development to expand menu Limited training required for customers already familiar with the LightCycler® 480 Analyzer The cobas z 480 Analyzer will offer the flexibility for you to design your own assays. The system contains a software for user defined workflow used for user to defined applications. When starting up the system the operator chooses to enter into the IVD software for HPV and CT/NG testing or the User Defined Workflow for laboratory developed tests. © 2014 Roche

Daily Maintenance – The cobas 4800 system requires minimal steps for daily maintenance which consist of examining the deck and cleaning any spills that may be on the deck, emptying the liquid waste, and emptying the tip waste if necessary. This step typically takes 2 – 7 minutes. Load cobas x 480 – Loading of consumables, specimens, and reagents; everything required for the run including the work order. This step can take 16 – 30 minutes depending on the size of the batch; 24 tests vs 96 tests. Sample Preparation – Automated total nucleic acid extraction and isolation by the cobas x 480 instrument. This includes the making of the master mix and pipetting of processed specimen into the AD plate for Real-Time PCR. This is an automated step that enables the operator to walk away from the system and perform other tasks. The processing time will vary dependent on the specimen type as well as the batch size. Sample processing for a 24 test batch of swabs and urine specimens for CT/NG testing takes 102 minutes and a batch of 96 samples will take approximately 167 minutes. Unloading of the cobas x 480 analyzer takes approximately 5 – 8 minutes and takes place in parallel with the start up of the cobas z 480 analyzer. Transfer to cobas z 480 – At the completion of sample processing the operator places a seal on the completed AD plate and transfers the plate to the cobas z 480 analyzer. Typically sealing the plate and loading the plate in the cobas z 480 analyzer will take 1 – 2 minutes. Amplification and detection is another walkaway step where the operator is free to perform other tasks in the laboratory. Amplification and detection is always the same regardless of batch size or specimen type; 86 minutes for CT/NG and 120 minutes for HPV. When the run is complete the operator removes the plate from the cobas z 480 analyzer and disposes of the plate. Typically this clean up step takes about 1 minute. Source: Argent Global Services

The first run of 24 samples are completed in just under 4 hrs; 22 patient results with one positive and one negative control. Once specimen preparation is complete and the plate has been loaded in the cobas z 480 analyzer the operator is able to begin another sample preparation on the cobas x 480 instrument. Following specimen preparation the operator must unload the cobas x 480 instrument. This unloading takes about 5 minutes, then the operator is able to begin loading the next run. The cobas x 480 instrument only requires daily maintenance every 24 hrs., so no maintenance or cleaning is required between runs. The internal clock on the cobas x 480 instrument will track the time for maintenance and can be seen on the status screen of the system software. Source: Argent Global Services, 2012

The cobas HPV Test was compared to the hc2 test with the Rapid Capture system and the Cervista® HPV Test and the Tecan DNA Extractor with the ABI 9700 Thermalcycler. # of reportables: Note the difference between the assays. The hc2 test requires 8 controls and calibrators reducing the number of results to 88 per 96 well plate. The Cervista assay uses 3 wells per sample reducing the throughput to 27 samples per plate, in this run 2 plates of samples were performed. Total cycle time: The cycle for the cobas HPV Test is about 27% faster than the other tests. Hands on Time: The cobas HPV Test provides full automation of sample preparation with real time PCR requiring 80% less user interventions The next slide shows a graphical illustration of this comparison. *Cervista hrHPV test performed on the Tecan DNA Extractor with the ABI 9700 Thermalcycler ** hc2 HPV test performed with the Rapid Capture System Source: HPV Comparison Study; Argent Global Services, 2010

Reduced time to results with minimal hands on time Includes daily maintenance You can clearly see the improved efficiency of the cobas HPV Test. Walk away time: People often talk about the amount of walk away time and the ability to free staff up to perform other duties in the laboratory. It is just as important to compare cycle time with walk away time. Longer the cycle time can create longer walk away time. Sounds good, but that means the time to result is longer as well. This slide demonstrates the importance of comparing all aspects of testing. The cobas HPV Test combined with the cobas 4800 system automation provides efficiency in total cycle time which will impact your time to results. This system has the shortest cycle time with the least amount of hands on time allowing for the operator to be free; attending to critical lab functions 90% of the time. cobas HPV test hc2 HPV test Cervista hrHPV test # of Reportables 94 88 48 Hands-On Time (min.) 33.17 149.02 129.01 Total Cycle Time (min.) 299.71 416.5 476.64 Walk-Away Time (% of Total) 90% 62% 66% Source: HPV Comparison Study; Argent Global Services, 2010
