General Cell Proliferation Parameter Calculators
Select the following three calculators for free online computation of useful parameters for general cell culture proliferation studies:
I. PDT – Population doubling time
II. PD – Population doublings
III. CPD – Cumulative population doublings
Note: A new ASTM-I Standard (F3716-25) is now available for CPD studies.
