This Human Pigment Epithelium-Derived Factor (Serpin F1) ELISA Kit from Innovative Research is intended for quantitative detection of human PEDF in cell culture supernates, cell lysates, serum and plasma (heparin, EDTA). Strip well format. Reagents for up to 96 tests.

This human PEDF ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A polyclonal antibody from goat specific for PEDF has been precoated onto 96-well plates. Standards(NSO, M1-P418) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for PEDF 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 substrate 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 PEDF amount of sample captured in plate.

Additional Information:

The capture antibody is a polyclonal antibody from goat, the detection antibody is a biotinylated polyclonal antibody from goat. Expression system for standard: Pigment epithelium-derived factor (PEDF) is also known as serpin F1 (SERPINF1). In humans, it is encoded by the SERPINF1 gene. PEDF has a variety of functions including antiangiogenic, antitumorigenic, and neurotrophic properties. It suppresses retinal neovascularization and endothelial cell proliferation. And Antiangiogenic function is also conferred by PEDF through inhibition of both VEGFR-1 and VEGFR-2. In addition, the antitumorigenic effects of PEDF are not only due to inhibition of supporting vasculature, but also due to effects on the cancer cells themselves. PEDF is shown to inhibit cancer cell proliferation and increase apoptosis via the FAS/FASL pathway. Expression of PEDF in the human retina is found at 7.4 weeks of gestation, suggesting it may play a role in retinal neuron differentiation.; Immunogen sequence: 369
