Hamster PCSK9 Protein (Hamster PCSK9, His Tag) Gln 30 - Ser 691 (Accession # G3GTK5) was produced in human 293 cells (HEK293) at ACROBiosystems.

Molecular Characterization

PCSK9 (Gln 30-Ser 691)G3GTK5


Hamster PCSK9, His Tag is fused with a polyhistidine tag at the C-terminus, and has a calculated MW of 73 kDa. The predicted N-terminus is Gln 30. The reducing (R) protein migrates as 18 kDa and 65 kDa in SDS-PAGE due to glycosylation and proteolytic digestion.


Less than 1.0 EU per μg by the LAL method.


>95% as determined by SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Trehalose are added as protectants before lyophilization.

See Certificate of Analysis for reconstitution instructions and specific concentrations.


Avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:
In lyophilized state for 1 year (4°C); After reconstitution under sterile conditions for 3 months (-70°C).



Hamster PCSK9 Protein

Hamster PCSK9, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.


Immobilized Human LDL R (High Purity) Protein, Strep Tag (Cat# LDR-H5281) at 5 μg/mL (100 μl/well) can bind Hamster PCSK9 Protein, His Tag (Cat# PC9-H52E4) with a linear range of 6-50 ng/mL.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is also known as NARC1 (neural apoptosis regulated convertase), is a newly identified subtilase belonging to the peptidase S8 subfamily. Mouse PCSK9 is synthesized as a soluble zymogen, and undergoes autocatalytic intramolecular processing in the endoplasmic reticulum, resulting in the cleavage of its propeptide that remains associated with the secreted active enzyme with a broad alkaline pH optimum. 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).
