Abstract
Reagents, methods, and kits are described that are useful for fertility testing and that in many cases provides much faster, convenient and rapid determination of male infertility. The reagents described include properly glycosylated human ZP3, ZP2, ZP1, glycosylated peptides thereof, fusion proteins such as green fluorescent protein—ZP3, non-covalent complexes of ZP2 with ZP3, fusion protein of ZP2–ZP3, solid phase materials such as agarose beads coated with binding agents such as ZP3, and other artificial zona. Methods are provided that, in many cases convert a complex biological event into a well defined biochemical binding event based on one or more of the reagents. Such methods are much easier to set up and monitor, allowing more convenient and inexpensive diagnostic testing for male fertility. The acrosome reaction is detected in other embodiments by virtue of quantitating one or more released substances. Kits are further provided that contain one or more reagents useful for testing at a diagnostic laboratory or other facility.
