The mammalian zona pellucida, which mediates species-specific sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy, is composed of three to four glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP2 may act as a secondary sper
Kit Principle
Genway Biotech Zp2 ELISA Kit (Rat) (GWB-KBBUU3) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for Zp2 has been pre-coated onto a 96-wellplate (12 x 8 Well Strips) and blocked. Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for Zp2 is added, incubated and followed by washing. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes to yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm is quantitatively proportional to the amount of sample Zp2 captured in the well.
