the resulting mouse anti-hybrid cell antisera contain antibodies found to be human specific and to react with only those hybrid cells carrying the human x chromosome , as confirmed by essentially perfect concordance between antibody binding assayed by indirect immunofluorescence and presence of the human x-linked enzyme hypoxanthine phosphoribosyl-transferase determined by autoradiographic assay of [ 3h ] hypoxanthine utilization .
