IC50 inhibitory concentration 50% --- the concentration at which
growth or activity is inhibited by 50%. Applies to ligand and growth inhibition.
ED or EC Effective dose (or concentration).
LD Lethal dose. LD50 --- the dose at which 50% of test subjects die.
GI50 growth inhibition 50% --- the drug concentration giving a 50% reduction int
the net protein increase.
LC50 for drugs with cytotoxic effect, is the concentration of drug
where 50% of cells die (a 50% reduction in the measured protein at the end
of the drug treatment as compared to that at the begining).
TGI total growth inhibition.
