This protein carries a polyhistidine tag at the C-terminus. This protein undergoes autocatalytic cleavage to release the pro-peptide and mature chain. The pro-peptide and mature chain are associated through non‑covalent interactions and with a calculated MW of 13.8 kDa and 58.1 kDa respectively. The protein migrates as 20 kDa and 65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>97% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human 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 97%.
Loaded Human LDL R, Fc Tag (Cat. No. LDR-H5254) on Protein A Biosensor, can bind Human PCSK9, His Tag (Cat. No. PC9-H5223) with an affinity constant of 4.39 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
FACS analysis shows that Human PCSK9, His Tag (Cat. No. PC9-H5223) inhibits LDL uptake in HepG2 cells. The EC50 for this effect is 0.2857-0.4668 μg/mL.
