Rat PCSK9, His Tag (PC9-R52H4) is expressed from human 293 cells (HEK293). It contains AA Gln 31 - Gln 691 (Accession # NP_954862.2).

Predicted N-terminus: Gln 31

Molecular Characterization

PCSK9(Gln 31 - Gln 691)NP_954862.2

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 73.2 kDa. The protein migrates as 22 and 66 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation.


Less than 1.0 EU per μg by the LAL method.



>97% as determined by reduced SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in PBS,pH7.4. Normally trehalose is added as protectant before lyophilization.

Proprotein convertase subtilisin/kexin type 9 (PCSK9), is an enzyme which in humans is encoded by the PCSK9 gene.This gene encodes a proprotein convertase belonging to the proteinase K subfamily of the secretory subtilase family. This protein plays a major regulatory role in cholesterol homeostasis. PCSK9 binds to the epidermal growth factor-like repeat A (EGF-A) domain of the low-density lipoprotein receptor (LDLR), inducing LDLR degradation. PCSK9 may also have a role in the differentiation of cortical neurons. Mutations in this gene have been associated with a rare form of autosomal dominant familial hypercholesterolemia (HCHOLA3).
