Ovalbumin Specific Immunoglobulin G (OVA sIgG) ELISA Kit for Human

Principle of the Assay: OVAsIgG ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-OVAsIgG antibody and an OVAsIgG-HRP conjugate. The assay sample and buffer are incubated together with OVAsIgG-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 OVAsIgG concentration since OVAsIgG from samples and OVAsIgG-HRP conjugate compete for the anti-OVAsIgG antibody binding site. Since the number of sites is limited, as more sites are occupied by OVAsIgG from the sample, fewer sites are left to bind OVAsIgG-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The OVAsIgG concentration in each sample is interpolated from this standard curve.

Small volumes of OVA sIgG elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS727058 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Ovalbumin specific Immunoglobulin G (OVA sIgG) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing OVA sIgG. The ELISA analytical biochemical technique of the MBS727058 kit is based on OVA sIgG antibody-OVA sIgG antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect OVA sIgG antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, OVA sIgG. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).
