if you have access to a fluorescent plate reader then the membrane
permeant DNA binding dye Hoechst 33258 can be used. It is much quicker
(freeze/thaw lysis=1h, incubate with dye, read). You will have to
standardise the fluor. unit with cell number at some point but once
that is in place, it should be pretty straight forward
It is not as sensitive in terms of raw numbers (for my cell types I
get an increase of about 600 AFU over 2 orders of magnitude of cells
(1000-100000)/well) as thymidine, but if you can use this technique I
think it is a lot easier.
