Product Information
KE00278 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The PCSK9 ELISA kit is to be used to detect and quantify protein levels of endogenous PCSK9. The assay recognizes human PCSK9. An antibody specific for human PCSK9 has been pre-coated onto the microwells. The human PCSK9 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase (HRP)-conjugated antibody specific for human PCSK9 is added to detect the captured human PCSK9 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.

Background Information
PCSK9, also named as NARC1 and PC9, belongs to the peptidase S8 family. PCSK9 is expressed and secreted by several tissues but principally by the liver, small intestines, and kidney (PMID 28587771). It may be implicated in the differentiation of cortical neurons and may play a role in cholesterol homeostasis. PCSK9 is a regulator of the LDL receptor and plasma cholesterol concentrations (PMID: 26293463).
