Description

Proprotein convertase subtilisin/kexin 9 (PCSK9) belongs to the proteinase K subfamily of subtilases and is expressed as a soluble zymogen that undergoes autocatalytic intramolecular processing in the endoplasmic reticulum. It is a 692 amino acid (aa) glycoprotein with an overall domain structure similar to other proprotein convertase members. It is comprised of a signal peptide (aa 1–30), a pro segment (aa 31–152), a catalytic domain (aa 153–407), a hinge region (aa 408–452), and a C-terminal Cys-His-rich domain (aa 453–692).

The biological roles of PCSK9 are closely related to its binding partners, low-density lipoprotein (LDL) and LDL receptor (LDLR). At the cell surface, secreted PCSK9 binds at a neutral pH to the EGF-A-like repeat of the LDLR via its catalytic domain. The binding of PCSK9 to LDLR enhances the degradation of the LDLR in endosomes/lysosomes, which results in increased circulating LDL-cholesterol (LDL-C). Thus, PCSK9 has gained attention as a pharmacological target for cardiovascular diseases and atherosclerosis. It also binds to the Apoliprotein B (ApoB) in LDL, although its role in this complex is not clearly understood. Due to the interaction of PCSK9 with LDLR, the levels of free PCSK9 or its complexed forms are important indicators for measuring risk of cardiovascular diseases or response to a therapy.

Application

ELISA Detection - Quality tested

Recommended Usage

Each lot of this antibody is quality control tested by ELISA assay. For ELISA Detection applications, a concentration range of 0.1 - 1.0 µg/mL is recommended. To obtain a linear standard curve, serial dilutions of PCSK9 recombinant protein ranging from 58.6 to 3750 pg/mL is recommended for each ELISA plate. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

The biotinylated Poly5250 antibody is useful as the detection antibody in a sandwich ELISA assay, when used in conjunction with purified M1118E3 antibody (Cat. No. 537502) as the detection antibody and Recombinant Human PCSK9 (ELISA Std.) (Cat. No. 592509)
