Human CD22 ELISA Kit

KE00131 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The CD22 ELISA kit is to be used to detect and quantify protein levels of endogenous CD22. The assay recognizes human CD22. An antibody specific for CD22 has been pre-coated onto the microwells. The CD22 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for human CD22 is added to detect the captured human CD22 protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450nm with the correction wavelength set at 630 nm.
