P1 Plaque Assay 11/5/2018

Rationale: perform plaque assay with plaque 1 to produce first plate with phage

Process:

  1. picked a plaque from Melissa’s plate with phage
    1. touched pipette tip to the center of plaque
      1. touched a little bit of the surrounding arthrobacter
    2. swirled tip into tube filled with 70 µL of phage buffer
  2. Added 30 µL of phage buffer + phage lysate into o.5 mL arthro and let sit for 15 minutes
  3. Made LB agar media for 3 plaque assay plates (control, 2 samples)
    1. Reagents Amount
      LB Broth 6 mL
      2X TA 7.5 mL
      1M CaCl2 68 µL
  4. Poured 5 mL of media into two separate tube for sample plates
    1. Ended up disposing of one of the tubes
  5.  Poured Arthro and lysate mixture into a LB agar sample tube
  6. Poured contents of tube onto a plate
  7. Poured the contents of the remaining LB agar media onto control plate
  8. Let solidify for ~15 minutes
  9. Incubate for 48 hours at 28 degrees C

 

Next Steps: calculate titer of lysate and perform another plaque assay to get a higher titer.
