Passaging cells calculations
WebSep 29, 2024 · Here’s how. Use the formula below: PDL = PDL 0 + 3.322 (logC f – logC i) Where: PDL0 = initial population doubling level Ci = initial cell number seeded into vessel Cf = final cell yield, or the number of cells at the end of the growth period Most labs start counting MSC cumulative population doublings after the P 0 cell harvest. WebOct 22, 2010 · 1) count the cells and split by cell numbers – like 1 X10^6 cells total in a T75 flask or 0.5 X 10^5 cells total in T75 flask. 2) number of cells / area (cm2) For example: 1 X 10^5 cells/cm2 = for a T75 it would be 75 X10^5 or 7.5 X10^6 cells total (we did this for human embryonic stem cells) 3) By Splitting ratios: This is the easiest of all.
