Cell Culture Doubling Time
Doubling time, specific growth rate, and number of doublings from two counts (or ODs) and the elapsed time (Td = t x ln2 / ln(N/N0)). Valid only in log phase; a span across lag or stationary phase is meaningless.
Formula and source
Td = elapsed x ln(2) / ln(N / N0); mu = ln(N / N0) / elapsed; doublings = log2(N / N0).
Exponential-growth / population-doubling kinetics (standard growth analysis), by name.
