Assay Principle
This sandwich ELISA quantifies equine fibroblast growth factor 1 (gene FGF1) in cell culture supernatants, serum and plasma (heparin, EDTA). Strips are pre-coated with a capture antibody. After the sample is added, a biotinylated detection antibody binds the captured protein, and an avidin–biotin–peroxidase complex supplies the enzyme. TMB develops color in proportion to the bound target; the reaction is stopped and read at 450 nm, and concentrations are read from the standard curve.
Fibroblast growth factor 1 (FGF1, acidic FGF) is a heparin-binding growth factor that activates all FGF receptors. It lacks a classical signal peptide but acts as a potent mitogen, and it regulates cell proliferation, survival, migration, differentiation and angiogenesis. FGF1 is studied in tissue repair, development and metabolic regulation.
