Product overview
Abcam’s TGF beta 1 Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of TGF beta 1 concentrations in cell culture supernatants.
A TGF beta 1 specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a TGF beta 1 specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of TGF beta 1 captured in plate. This assay recognizes both natural and recombinant Human TGF beta 1.
The entire kit may be stored at -20°C for long term storage before reconstitution – Avoid repeated freeze-thaw cycles.
