Hi Jess,

If you are using a cell line to monitor effects of a drug my question would
be why do you need a normal population of cells? Even though your cell line
is presumably transformed and may well be aneuploid, the control for your
experiment would be a normal exponentially growing sample of the cell line.
This will have a G1 peak, S phase and G2 - they may not be in the same
place as 'normal' lymhocytes but you would be able to see your drug effects
compared to your untreated control

Derek.
