Abstract
A study of the apurinic/apyrimidinic (AP) endonuclease activities of a mutant line of CHO cells, EM9, and its parental cell line, AA8, was undertaken to determine if the defective DNA repair exhibited by the mutant cell line after exposure to ethyl methanesulfonate was due to a defective AP endonuclease activity. Phosphocellulose chromatography of cell extracts resolved the AP endonuclease activities of both cell lines into two peaks as seen previously in mouse and human cells. No difference was found between the mutant and parental cell lines in the relative amount of AP endonuclease activity present in the two peaks.
