Abstract A technique for fluorescence staining of X and Y bodies (sex chromatin) after antibody- and complement-mediated cytotoxicity test has been developed. Cytotoxicity was quantitated by staining the dead cells with trypan blue (dye exclusion test). X bodies (Barr bodies) of human female fibroblast (stained with acridine orange) were observed in about 40 percent of the cells which survived cytotoxicity. Y bodies were studied on human male fibroblasts and in a hamster/human hybrid line which retained the human Y chromosome only. Fluorescent Y body was detectable in from 50 to 60 percent of the cells which survived the serological test. The double staining procedure did not significantly affect the proportion of killed (trypan blue-positive) cells. We suggest that this is a useful method for the detection of cytotoxic antibodies against the products of X and Y chromosomes, especially when mixed cell populations-such as tumor, sex chromosome mosaics, sperm, and artificially mixed human male and female cell lines-are tested.
