The doubling time is defined as the time required for the number of cells in the popu­lation to double during exponential growth. Many cell biologists use the term generation time interchange­ably with doubling time. Strictly speaking, however, the generation time is the interval of time between any point in one cell cycle (see later) and the resuspend the cells in 1 or 2 mL of complete growth medium. Transfer the cell suspension into the culture vessel containing the complete growth medium and mix thoroughly by gentle rocking. 5 Examine the cell cultures after 24 hours and subculture as needed.

Simplify downstream protein purification with serum-free CHO MediumGet optimal expression of recombinant proteins Select from chemically defined, protein-free, and serum-free formulations (Table 1) Choose media for suspension or adherent cells Furthermore, based on the cell number and CI values in Fig. 3B, researchers estimated that the doubling time for U2OS cells is 23.7±0.5 h or 24.1±0.6 h for cells cultured in regular 96-well plates and in RT-CES devices, respectively."

To calculate the doubling time, use the following formula: Doubling Time = [ T × ( ln2 ) ] / [ ln (Xe / Xb) ] where T = Time in any units. Example. Let’s say that on Day 0, you count 2 × 10 6 cells.
