Abcam’s FGF9 Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human FGF9 in plasma and cell culture supernatants. (Human FGF9 concentration is pretty low in normal plasma, it may not be detected in this assay).
This assay employs an antibody specific for Human FGF9 coated on a 96-well plate. Standards and samples are pipetted into the wells and FGF9 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human FGF9 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of FGF9 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
We have not been able to detect the endogenous Human FGF9 in normal serum with ab100520, only in serum spiked with Human FGF9.
Optimization may be required with urine samples.
