The ELISA kits listed below target PCSK9, the symbol for the human gene, proprotein convertase subtilisin/kexin type 9, and a member of the Peptidase S8 family. The protein has an enzyme classification of peptidase (broad). The protein encoded by PCSK9 has a predicted amino acid length of 692, a mass of 74.3 kDa, and a cytoplasmic and secreted subcellular localization. There are currently 2 reported isoforms, as well as sites of glycosylation. Pathologic involvement is reported in Hypercholesterolemia, autosomal dominant, 3. PCSK9 may also be known by the following names: LDLCQ1, HCHOLA3, FH3, subtilisin/kexin-like protease PC9, neural apoptosis regulated convertase 1, and convertase subtilisin/kexin type 9 preproprotein, and NARC1. Orthologs of the gene, including human, mouse, rat, bovine, chicken, primate, guinea pig, fish, plant, and other mammalian are available targets of several ELISA kits.
