Growth rate and doubling time

Calculate the growth rate or doubling time of your cell culture with this tool. Which of the two you need mostly depends on your lab’s practice, as they are interchangeable.

Growth rate and doubling time are valuable measures to characterize your cell lines and culture conditions, to compare cell lines and plan future experiments.

 

cell culture growth rate doubling time

r = growth rate [1/d]

t = hours of growth [h]

N0 = number of cells seeded

Nt = number of cells harvested

td = doubling time [h]

    \[r=\frac{ ln\left( \frac{ N_t }{ N_0 } \right)}{ t}\cdot24h\]

 

    \[t_d=\:\frac{ln(2)}{r}\cdot24h\]
