P1 Plaque Assay 11/5/2018
Rationale: perform plaque assay with plaque 1 to produce first plate with phage
Process:
- picked a plaque from Melissa’s plate with phage
- touched pipette tip to the center of plaque
- touched a little bit of the surrounding arthrobacter
- swirled tip into tube filled with 70 µL of phage buffer
- touched pipette tip to the center of plaque
- Added 30 µL of phage buffer + phage lysate into o.5 mL arthro and let sit for 15 minutes
- Made LB agar media for 3 plaque assay plates (control, 2 samples)
-
Reagents Amount LB Broth 6 mL 2X TA 7.5 mL 1M CaCl2 68 µL
-
- Poured 5 mL of media into two separate tube for sample plates
- Ended up disposing of one of the tubes
- Poured Arthro and lysate mixture into a LB agar sample tube
- Poured contents of tube onto a plate
- Poured the contents of the remaining LB agar media onto control plate
- Let solidify for ~15 minutes
- Incubate for 48 hours at 28 degrees C
Next Steps: calculate titer of lysate and perform another plaque assay to get a higher titer.
