Human GRP ELISA Kit

KE00070 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The GRP ELISA kit is to be used to detect and quantify protein levels of endogenous GRP. The assay recognizes human GRP. An antibody specific for GRP has been pre-coated onto the microwells. The GRP protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for GRP is added to detect the captured GRP 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 450nm with the correction wavelength set at 630 nm.
