Monoclonal antibodies against boar sperm zona pellucida-binding protein AWN-1. Characterization of a continuous antigenic determinant and immunolocalization of AWN epitopes in inseminated sows.
Boar spermadhesin AWN-1 is a sperm surface-associated 14.7-kDa lectin and a major protein of porcine seminal plasma. AWN-1 binds to beta-galactosides and to porcine zona pellucida glycoproteins, suggesting that this protein might play a role in the primary binding of spermatozoa to the egg's external glycoprotein matrix. We have produced a collection of murine monoclonal antibodies against puri...
متن کاملInhibition of goat sperm-zona binding by monoclonal antibodies to a glycoprotein family (ZP4) of porcine zona pellucida
The zona pellucida (ZP) in a majority of species consists of three antigenic families with wide inter species cross reactivity. The glocoproteins of heat solubilized goat zona pellucida (gZP) were isolated into three families by high performance liquid chromatography on a gel ®ltration column. Their molecular identities were 180, 95 and 75 kDa for gZP1, gZP2 and gZP3 respectively. However under...
متن کاملProduction and immunolocalization of monoclonal antibodies against human sperm
In order to help identify and characterize antigens involved in sperm functions and immune infertility, monoclonal antibodies (mAbs) were raised against human sperm surface antigens. The IgG fraction of serum from a donor with a spontaneous high titer of IgG-positive antisperm reactivity (as determined by immunobead binding) was purified by ammonium sulfate precipitation. This IgG preparation w...
متن کاملBinding of zona pellucida proteins to a boar sperm polypeptide of Mr 53,000 and identification of zona moieties involved.
Experiments have been carried out to identify proteins on boar spermatozoa that bind to components of the zona pellucida. Polypeptides in sodium deoxycholate extracts of boar spermatozoa and in whole seminal plasma have been separated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis, transferred onto nitrocellulose sheet by electroblotting and probed with 125I-labelled heat-solubil...
متن کاملRole of sialic acid in bovine sperm-zona pellucida binding.
Sperm binding activity has been detected in zona pellucida (ZP) glycoproteins and it is generally accepted that this activity resides in the carbohydrate moieties. In the present study we aim to identify some of the specific carbohydrate molecules involved in the bovine sperm-ZP interaction. We performed sperm binding competition assays, in vitro fecundation (IVF) in combination with different ...
