Measurement of poly (ADP-ribose) levels was performed by a new method using a monoclonal antibody against poly (ADP-ribose) and flow cytometry from small amount of cultured cells without the need for isolation of poly (ADP-ribose) polymer. The increase of poly (ADP-ribose) -associated fluorescence intensity was observed in individual human leukemic HL-60 cells when treated with the carcinogen, N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), and was blocked by the treatment with 3-aminobenzamide before MNNG treatment. It is easy and rapid to detect the time-dependent change of poly (ADP-ribose) levels in HL-60 cells after MNNG treatment. We easily found that the increase of the poly (ADP-ribose) level in nicotinic acid-treated lymphocytes after MNNG treatment was observed, but not in nicotinamide-treated lymphocytes. We investigated the change of poly (ADP-ribose) levels especially in the early phase of apoptosis. Our method is simple and rapid. It is suggested that the investigation of poly (ADP-ribosyl) ation in various fields is possible by using this new method.
