Active Recombinant Human CFD protein, His-tagged

• Cat.No.: CFD-187H
• Product Overview: Recombinant Human CFD protein( Ile 26 - Ala 253 ), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH8.0. Normally glycerol is added as protectant before lyophilization.
• Bio-activity: Measured by its ability to cleave a colorimetric peptide substrate, N-carbobenzyloxy-Lys-ThioBenzyl ester (Z-Lys-SBzl), in the presence of 5,5’Dithio-bis (2-nitrobenzoic acid) (DTNB). The specific activity is >80 pmol/min/μg.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus.The protein has a calculated MW of 26.3 kDa. The protein migrates as 28 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
• Protein Length: Ile 26 - Ala 253
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after storage 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.
