GENDER SELECTION WITH THE USE OF ANTIBODIES

摘要

Epitope polypeptides, corresponding to antigenic regions of hydrophilic sequences selected from within mammalian gene Y-chromosome protein sequences, have been prepared and used to generate antibodies in vivo. The antibodies have been found to bind preferentially to the Y-chromosomal sperm component in semen. The binding has been found sufficient to decrease motility of such Y-chromosomal sperm component leading to substantial increases in female offspring when using the treated semen in artificial insemination.
