Mouse IgG2b ELISA Kit from Innovative Research is a highly sensitive two-site enzyme linked immunoassay (ELISA) for measuring Mouse IgG2B in biological samples. Strip well format. Reagents for up to 96 tests. In this assay the IgG2B present in samples reacts with the anti-IgG2B antibodies which have been adsorbed to the surface of polystyrene microtitre wells. After the removal of unbound proteins by washing, anti-IgG2B antibodies conjugated with horseradish peroxidase (HRP), are added. These enzyme-labeled antibodies form complexes with the previously bound IgG2B. Following another washing step, the enzyme bound to the immunosorbent is assayed by the addition of a chromogenic substrate, 3,3Æ,5,5Æ-tetramethylbenzidine (TMB). The quantity of bound enzyme varies directly with the concentration of IgG2B in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of IgG2B in the test sample. The quantity of IgG2B in the test sample can be interpolated from the standard curve constructed from the standards, and corrected for sample dilution. Detection Target: IgG2b Reactivity: Mouse Range: 6.25 ng/ml - 200 ng/ml Sensitivity: 0.878 ng/ml Storage Conditions: 4C At Innovative Research, we provide reliable, consistent products that deliver reliable, consistent results.
