- Figure 1. On-screen growth chart and results of the K562 cell in the Bioprocess Review. (A) The growth chart is showing the cumulative results of cell concentration over date. (B) Summarized results show the start date, the number of measurements, current growth rate, doubling time, current concentration, and viability.
Table 1. The report in Fluorescence Cell Counting Mode. The
example CSV report from the HL60 batch run. The report contains date, time,
concentration and viability. The data of escape time, growth rate, and doubling time are
calculated from the last count (Blue shadows) and the run’s total time (Green shadows).
*Growth rate per hour = (LN V2 – LN V1) / (t2 – t1)
**Doubling time in hours = LN (2) / Growth rate per hour
LN = Natural log,
t1, t2 = Unit of hour,
V1 = Cell concentration in cells/mL at elapsed time t1 in hours,
V2 = Cell concentration in cells/mL at elapsed time t2 in hours
