INTENDED USE This TGL ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Monkey TGL. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
PRINCIPLE OF THE ASSAY TGL ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-TGL antibody and an TGL-HRP conjugate. The assay sample and buffer are incubated together with TGL-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the TGL concentration since TGL from samples and TGL-HRP conjugate compete for the anti-TGL antibody binding site. Since the number of sites is limited, as more sites are occupied by TGL from the sample, fewer sites are left to bind TGL-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The TGL concentration in each sample is interpolated from this standard curve
