Recombinant Human CD200 protein, Fc-His-tagged

• Cat.No.: CD200-629H
• Product Overview: Recombinant Human CD200 protein(NP_005935.4)(Met 1-Gly 232) was expressed in HEK293, fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc&His
• Protein Length: 1-232 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: Measured by its binding ability in a functional ELISA. Immobilized human CD200R1 at 1 μg/ml (100 μl/well) can bind human CD200 Fc Chimera with a linear range of 0.12-16 ng/ml.
• Molecular Mass: The recombinant human CD200/Fc is a disulfide-linked homodimer. The reduced monomer consists of 450 amino acids and has a predicted molecular mass of 50.5 kDa. As a result of glycosylation, the apparent molecular mass of rh CD200/Fc monomer is apximately 65-70 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.
• 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.
