This Human Pregnancy Zone Protein ELISA Kit from Innovative Research is intended for quantitative detection of human PZP in cell culture supernates, serum and plasma (heparin, EDTA). Strip well format. Reagents for up to 96 tests.

This human PZP ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from human specific for PZP has been precoated onto 96-well plates. Standards(Expression system for standard: NSO, Immunogen sequence: T26-V1482) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for PZP is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substmousee TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human Fibronectin amount of sample captured in plate.

Additional Information:

The capture antibody is a monoclonal antibody from mouse, the detection antibody is a biotinylated detection polyclonal antibody from goat. Expression system for standard: Pregnancy zone protein (PZP) is a protein which in humans is encoded by the PZP gene on chromosome 12. It is mapped to 12p13.31. The protein encoded by this gene is highly expressed in late-pregnancy serum and is similar in structure to alpha-2-macroglobulin. The encoded protein, which acts as a homotetramer, inhibits the activity of all four classes of proteinases. This protein contains cleavage sites for several proteinases. Upon binding of a proteinase, the conformation of this protein changes to trap the proteinase, limiting its activity. This protein appears to be elevated in the sera of presymptomatic Alzheimer's disease patients.; Immunogen sequence: 369
