1.Infection 2.Amplification 3.Morphogenesis + release of progeny phage new M13 phage particles within 10’ post-infection 1000 phage/cell within the first hour BioMaterials: Let’s start with the biology
6
Parts 2 + 3 of your experiment today Phage purification Harvest phage infected cells. Phage in SUPERNATANT! Concentrate by precipitation (+PEG/salt) Pellet may not be visible…have faith Plaque assay Serially dilute phage in water Mix with bacteria Add warm “top agar” and plate on LB--> 37° overnight Give remaining phage to Luis
7
BioMaterials: now for materials Oxidized (purple)Reduced (clear)
8
Part 1 of your experiment today Hydrolyze Iridium with citrate at 90° 4 hrs Generates Ir colloidal particles Next time will oxidize to form IrOx colloidal particles which can react with phage p8 You must wear safety glasses, gloves, lab coat to do this part of today’s experiment
9
FNT 1.Describe display technology 2.Choose research proposal (5 possible topics) or collaborative art/science option
