Site Remediation: Summary of Findings 3 Timeliness Viability/Recovery Annotation Instrument Setup Analysis Gating Including debris/dead cells/monocytes in gates Including Monocyte population - TNFa backgrounds Not including all of anchor gate populations Not including dim positives in anchor gate populations Setting cytokine gates too close/too far from negative Failing to backgate FlowJo Versions Performance (processor) Bugs

Elements of Data Analysis Compensation – electronic adjustment for spectral overlap – When to compensate Acquisition – if gating on #CD3+, requires compensation Off-line – Spillover Biexponential Transformation Gates Analysis Regions Backgating – used to tweak gates and analysis regions so as to optimize response (maximize positive and minimize negative responses) Acceptability criteria Inter-operator variability

Spectral Overlap

7 Compensation Cannot Correct Spreading Error

Spectral Overlap

Compensation: Inspect and Manually Correct as Needed PE-PEA610 = PE-PEA610 = 11 Auto Manually adjusted

Compensation: False Positive CD4 Response to CEF Pepmix mSA EOLm

Compensation: False Positive CD4 Response to CEF Pepmix

1. Compensation matrix

Original Matrix (Auto-comp) “Corrected” Matrix (Auto-comp w/ Manual tweaking) Note 1: Compensation pairs discussed during the call are marked with pink arrows. Red arrows indicate other compensation pairs I felt could benefit from manually tweaking compensation values. Note 2: flowjo automatically flags manual edits using red text; all other differences are flowjo doing weird rounding/display stuff (ex. for PEA610-PE “590” is really “59.36;” the value has not been modified… this drives me NUTS! Original vs Manually-tweaked FlowJo Compensation Values

CIC Gating Panel: Gating Recommendations

B (3.4%) F (10.5%) E (13.4%) D (10.2%)K (9.4%) G (16.9%) C (3.1%)A (6.8%) H (10.2%) I (12.7%) J (4.8%) Here labs are listed in order of their total TNF  response. It is visually apparent that, while all labs had overcompensation, it is worst in labs with the lowest cytokine responses.
