Active Recombinant Human TNFRSF1A protein, Fc-His-tagged

• Cat.No.: TNFRSF1A-3251H
• Product Overview: Active Recombinant Human TNFRSF1A protein(NP_001056.1)(Met 1-Thr 211) 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: 1-211 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: Measured by its ability to inhibit the TNF-α mediated cytotoxicity in the L-929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is typically 0.5-3 ng/ml in the presence of 1 ng/mL recombinant human TNF-α.
• Molecular Mass: The recombinant human TNFRI/Fc is a disulfide-linked homodimer. The reduced monomer consists of 438 amino acids and has a predicted molecular mass of 49.3 kDa. As a result of glycosylation, rh TNFRI/Fc monomer migrates with an apparent molecular mass of 60-65 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 90 % 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.
