Product Description |
Recombinant Cynomolgus PCSK9 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Glu151-Gln811. |
Product Background |
Proprotein convertase subtilisin/kexin type 9 (PCSK9) is an enzyme encoded by the PCSK9 gene in humans on chromosome 1.The first two PCSK9 inhibitors, alirocumab and evolocumab, were approved as once every two week injections, by the U.S. Food and Drug Administration in 2015 for lowering LDL-particle concentrations when statins and other drugs were not sufficiently effective or poorly tolerated. |

Molecular Weight |
Due to autocatalytic cleavage, the protein release the pro-form (59 kDa) and mature form (14 kDa). Due to glycosylation, the protein migrates to 65-70 kDa (pro-form) and 15-20 kDa (mature form) based on Bis-Tris PAGE result. |
