Human P21 ELISA Kit, 96 tests

KE00049 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The P21 ELISA kit is designed for the quantitative determination of P21 in samples of human origin. An antibody specific for P21 has been pre-coated onto the microwells. The P21 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for P21 is added to detect the captured P21 protein. For signal development, horseradish peroxidase (HRP)-conjugated antibody 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 450 nm with the correction wavelength set at 630 nm.
