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