Active Recombinant Cynomolgus PCSK9 protein, His-tagged

• Cat.No.: PCSK9-358C
• Product Overview: Recombinant Cynomolgus PCSK9 protein(Gln 31 - Gln 692), fused with His tag, was expressed in HEK293.

Specification

• Species: Cynomolgus
• Source: HEK293
• Tag: His
• Protein Length: Gln 31 - Gln 692
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose.
• Bio-activity: Immobilized Human LDL R, Fc Tag at 5 μg/mL (100 μL/well) can bind Cynomolgus PCSK9, His Tag with a linear range of 0.078-0.313 μg/mL.
• Molecular Mass: 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 13.9 kDa and 59.3 kDa respectively. The protein migrates as 17 kDa and 65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after at:
  -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
