KE00282 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The VISTA/C10orf54 ELISA kit is to be used to detect and quantify protein levels of endogenous VISTA/C10orf54. The assay recognizes human VISTA/C10orf54. An antibody specific for VISTA/C10orf54 has been pre-coated onto the microwells. The VISTA/C10orf54 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase (HRP)-conjugated antibody specific for VISTA/C10orf54 is added to detect the captured VISTA/C10orf54 protein. For signal development, 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.
