Active Recombinant Human C5 protein, His-tagged

• Cat.No.: C5-536H
• Product Overview: Recombinant Human C5 protein(Gln 19 - Cys 1676), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human Complement C5 (w917s), His Tag at 2 μg/mL (100 μL/well) can bind Anti-C5a MAb (Human IgG1) with a linear range of 0.2-6 ng/mL.Immobilized Human Complement C5 (w917s), His Tag at 2 μg/mL (100 μL/well) can bind Eculizumab Biosimilar with a linear range of 0.004-0.25 μg/mL.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus. The mature form of Complement C5 is a disulfide-linked heterodimer composed of proteolytically cleaved α and β chain. Each α and β chain has a calculated MW of 73.9 kDa (β chain) and 114.3 kDa (α chain). The protein migrates as 80 kDa (β chain) and 110 kDa (α chain) under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Proteinlength: Gln19-Cys1676
• 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.
• Protein length: 19-1676 a.a.
