Active Recombinant Human CD80, Fc-tagged, Biotinylated

• Cat.No.: CD80-582H
• Product Overview: The recombinant human CD80-Fc fusion protein is expressed as a 437 amino acid protein consisting of Val35 - Asn242 region of CD80 (UniProt accession #P33681) and a C-terminal Fc fusion from human IgG1, which exists as a dimer under non-reducing condition.

Specification

• Source: Human cells
• Species: Human
• Tag: Fc
• Form: Supplied at 0.5 mg/ml in sterile PBS pH7.4 (carrier free & preservative free). The purified recombinant protein was labeled with Biotin (3-5 Biotin per molecule).
• Bio-activity: Binds to human CD28, CTLA4 and PD-L1 by ELISA using immobilized CD80 protein. Binds to human and mouse PD-L1 in a functional ELISA. Induces IL-2 secretion by Jurkat human acute T cell leukemia cells with an ED50 of 0.05 - 0.2 μg/mL in the presence of PHA.
• Molecular Mass: Calculated molecular mass 49.5 kDa; estimated by SDS-PAGE under reducing condition 70-75 kDa probably due to glycosylation.
