Abstract
A newly developed enzyme-linked immunosorbent assay (ELISA) has been applied to the study of H-Y antigen in cases of XY, XYY, and X,dicY gonadal dysgenesis, testicular feminization syndrome, XXXXY syndrome, and XX true hermaphroditism. Monoclonal H-Y antibody was absorbed with cells from each of eight patients and from normal male and female controls, and then reacted with a plated antigen source in a system subsuming the addition of biotinylated secondary antibody, avidin-biotin-enzyme complex and substrate, and thereby the generation of a color. Positive absorption decreased the reaction, and this allowed sensitive measurement of H-Y phenotype in an electronic optical density reader. The ELISA obviates many of the technical difficulties encountered in complement-mediated cytotoxicity systems and can be used in the study of clinical cases of aberrant sex determination and in the evaluation of current models of the genetics of sex determination.
