Human SERPINA1 ELISA Kit

KE00178 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The SERPINA1 ELISA kit is to be used to detect and quantify protein levels of endogenous SERPINA1. The assay recognizes human SERPINA1. An antibody specific for SERPINA1 has been pre-coated onto the microwells. The SERPINA1 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody specific for SERPINA1 is added to detect the captured SERPINA1 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.
