This paper describes a 4'-6-diamidino-2-phenylindole (DAPI) fluorescent technique for differentiation of sister chromatids and for the study of sister chromatid exchanges (SCE) in mouse chromosomes. The advantages of the DAPI fluorescent technique are also described. Differences in the occurrence of

The ability of UV light, mitomycin C and ionizing radiation to induce the formation of sister chromatid exchanges (SCEs) at the same locus in successive cell generations was investigated in human lymphocytes. Cells were exposed to the DNA damaging agents after they had completed their first round of
By taking advantage of the fact that fluorescent light (FL) induces strand breaks only in bromodeoxyuridine(BrdUy-substituted DNA, and that those breaks eventually lead to the formation of sister chromatid exchanges (SCEs), the response of SCEs to FL was studied carefully in Chinese hamster chromoso
Studies are reported that are designed to analyze the mechanism by which caffeine reduces the induction of SCE by UV light or alkylating agents. The substantial points are (1) caffeine does not inhibit SCE formation, and (2) the caffeine-mediated apparent decrease of SCE induction after UV or triazi
