Cell Culture Fluid Changes and Primary Cell Culture Weeks of 20220516 and 20220523

A fluid change was performed on all flasks in the incubator on 20220516

  • 3mL fluid removed
  • 3mL new 20% FBS added

1 Myd88 secondary flask from 04/22 that was basically confluent was cell scraped, and separated out into 4 new flasks on 20220516

Primary cell culture on 20220523 and 20220524

  • For these cells, the egg laying scenario was slightly different:
    • Flies were put on plates in mid afternoon Saturday and left overnight
    • Then flies were swapped to a new plate in the morning on Sunday and left for 24 hours
    • Plates were not collected until at least 10:30am to facilitate morning laying
    • Then plates were left to “mature” (eggs to cellularize) for 2-3 hours after being taken off before the primary cell culture process began
    • The second cc plate was put on regularly
  • On 05/23 1 primary cc flask was make for IMD null flies, and 1 for innubila
  • On 05/10 3 primary cc flasks were make for IMD null flies, and 2 for innubila
  • These were done with the updated cell culture protocol
