Anti-Mouse Sperm Protein sp56 [Clone 5F12] - 100 μg

Mouse sperm recognize and bind to ZP3, one of three glycoproteins in the egg’s zona pellucida. Mouse Sperm protein sp56 has the characteristics expected of the sperm protein responsible for recognition of ZP3. Primary sequence data indicates that sp56 is a member of a superfamily of protein receptors. Expression of sp56 is restricted to mouse spermatids and is a peripheral membrane protein located on plasma membrane overlying the sperm’s acrosome. Native sp56 is expressed as a homomultimer.
