Active Recombinant Human ICOSLG, His-tagged, Biotinylated

• Cat.No.: ICOSLG-539H
• Product Overview: he recombinant human B7-H2/ICOSL/CD275 ECD is expressed as a 249 amino acid protein consisting of Asp19 - Thr256 region of B7-H2 (UniProt accession #O75144) and a C-terminal His-tag. It contains 6 potential sites for N-linked glycosylation.

Specification

• Source: Human cells
• Species: Human
• Tag: His
• Form: Supplied at 0.5 mg/ml in sterile PBS pH7.4 (carrier free). The purified recombinant protein was labeled with Biotin (3-5 Biotin per molecule).
• Bio-activity: Binds human ICOS and stimulates human T cell proliferation in the presence of anti-CD3.
• Molecular Mass: Calculated molecular mass 27.8 kDa; estimated by SDS-PAGE under reducing condition 50-60 kDa probably due to glycosylation.
