Assay Principle
This EZ-Set™ kit supplies a matched capture and detection antibody pair and a standard for building your own sandwich ELISA for human fibroblast growth factor 2 (gene FGF2) in cell culture supernatants, serum and plasma (heparin, EDTA). You coat the plate with the capture antibody, add samples and standards, detect with the biotinylated antibody and an avidin–biotin–peroxidase complex, develop with TMB and read at 450 nm. Plates, diluents, wash buffer, TMB and stop solution are not included.
Fibroblast growth factor 2 (FGF2, basic FGF) is a heparin-binding growth factor that activates FGF receptors 1–4. It is a potent mitogen that promotes cell proliferation, survival, migration and angiogenesis, and it is widely used as a supplement to maintain stem cells in culture. FGF2 is studied in development, tissue repair, angiogenesis and cancer.
