SpecificityThis assay has high sensitivity and excellent specificity for detection of HPF4Ab. No significant cross-reactivity or interference between HPF4Ab and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete thecross-reactivity detection between HPF4Ab and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseMouse HPF4Ab ELISA Kit allows for the in vitro quantitative determination of HPF4Ab , 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: HPF4Ab ELISA kit applies the competitive enzyme immunoassay technique utilizing Heparin Platelet Factor 4 antigen and an HPF4Ab-HRP conjugate. The assay sample and buffer are incubated together with HPF4Ab-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 HPF4Ab concentration since HPF4Ab from samples and HPF4Ab-HRP conjugate compete for the Heparin Platelet Factor 4 antigen binding site. Since the number of sites is limited, as more sites are occupied by HPF4Ab from the sample, fewer sites are left to bind HPF4Ab-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The HPF4Ab concentration in each sample is interpolated from this standard curve.
