Sex-associated membrane proteins and methods for increasing the probability that offspring will be of a desired sex
First Claim
1. A refined X sex-associated membrane protein characterized by a higher band density on an SDS/PAGE of plasma membrane proteins prepared from X-enriched sperm subpopulations as compared to the corresponding band density on an SDS/PAGE of plasma membrane proteins prepared from whole sperm or prepared from Y-enriched sperm subpopulations;
- or a refined Y sex-associated membrane protein characterized by a higher band density on an SDS/PAGE of plasma membrane proteins prepared from Y-enriched sperm subpopulations as compared to the corresponding band density on an SDS/PAGE of plasma membrane proteins prepared from whole sperm or prepared from X-enriched sperm subpopulations.

Abstract
A method of sorting living cells based on DNA content. Mammalian sperm subpopulations enriched in X- or Y-sperm. X- and Y-enriched sperm-plasma-membrane vesicles. Substantially pure sex-associated membrane (SAM) proteins. Antibodies binding to X-or Y-SAM proteins, essentially free of antibodies binding to Y- or X-SAM proteins respectively, or to the H-Y antigen. Semen samples enriched for X- or Y-sperm. Methods for increasing the probability that offspring will be male or female comprising the step of allowing as penn from an enriched semen sample to fertilize an ovum. Methods for increasing the probability that offspring will be male or female comprising the step of immunizing a female with X- or Y-SAM proteins. Methods of decreasing fertility comprising the step of immunizing a female with both X- and Y-sperm. Methods of increasing the probability that mammalian offspring will carry a gene for a particular sex-chromosome linked trait.
