Clonogenic assay
A clonogenic assay is a cell biology technique for studying the effectiveness of specific agents on the survival and proliferation of cells. It is frequently used in cancer research laboratories to determine the effect of drugs or radiation on proliferating tumor cells as well as for titration of Cell-killing Particles (CKPs) in virus stocks. It was first developed by T.T. Puck and Philip I. Marcus at the University of Colorado in 1955.
