SpecificityThis assay has high sensitivity and excellent specificity for detection of PROG. No significant cross-reactivity or interference between PROG and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between PROG and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseMouse PROG ELISA Kit allows for the in vitro quantitative determination of PROG , concentrations in serum, Plasma , tissue homogenates and Cell culture supernates and Other biological fluids.
StorageFor 5-7days:Store the whole kit at 4℃
For a Long time :Store the Substrate at 4℃, other reagent should store at -20℃.
Product Description specificalPrinciple of the assay: PROG ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-PROG antibody and an PROG-HRP conjugate. The assay sample and buffer are incubated together with PROG-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 PROG concentration since PROG from samples and PROG-HRP conjugate compete for the anti-PROG antibody binding site. Since the number of sites is limited, as more sites are occupied by PROG from the sample, fewer sites are left to bind PROG-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The PROG concentration in each sample is interpolated from this standard curve.
