SEPARATION OF MAMMALIAN SEMEN INTO FRACTIONS ENRICHED EITHER FOR SPERMATOZOA CONTAINING AN X CHROMOSOME OR FOR SPERMATOZOA CONTAINING A Y CHROMOSOME

摘要

The present invention relates to a method for the fractionation of semen which comprises contacting semem sample with a specific antibody preparation such that said antibody binds to spermatozoa bearing a Y chromosome, and thereafter separating antidody-spermatozoa complexes from unbound spermatozoa.
