ESTRUTURA ANTIGÊNICA DE SUPERFÍCIE DE CÉLULAS ESPERMÁTICAS ASSOCIADAS AO CROMOSSOMO Y, MOLÉCULAS DIRIGIDA ESPECIALMENTE CONTRA UMA ESTRUTURA ANTIGÊNICA, ESTOJO DE SEXAGEM, SUPORTE SÓLIDO E PROCESSO DE DISCRIMINAÇÃO ENTRE CÉLULAS ESPERMÁTICAS PORTADORAS DO CROMOSSOMO Y E CÉLULAS ESPERMÁTICAS PORTADORAS DO CROMOSSOMO X

摘要

Sperm cell surface antigen associated with the Y chomosome, with a molecular weight of 5-12 kD and an isoelectric point above 9, is new. Independent claims are also included for: (1) molecule (I) directed specifically against the antigen; (2) sex determination kit comprising (I) and optionally the antigen; (3) product comprising (I) immobilized on a solid support; (4) discriminating between sperm cells bearing a Y chromosome and sperm cells bearing an X chromosome by contacting the cells with (I) so that cells bearing a Y chromosome are labeled with (I), optionally separating the labeled cells from unlabeled cells, and optionally recovering the labeled or unlabeled cells.
