Description

Recombinant Protein

Recombinant Human B7-1Fc is a homodimeric B7-1 fusion protein, whose monomer contains a total of 441 amino acid residues, consisting of 211 amino acid residues corresponding to the extracellular domain of human B7-1, fused to the Fc portion of human IgG1. The calculated molecular weight of the B7-1 Fc monomer is 50.0 kDa. This product is shipped at ambient temperature. For storage, handling and reconstitution information, please see the lot-specific Certificate of Analysis

CD80 (B7-1) and CD86 (B7-2) are ligands of T cell critical costimulatory molecule CD28, and of an inhibitory receptor CTLA-4 (CD152). Both B7 molecules are expressed on professional antigen-presenting cells and are essential for T cell activation, and both molecules can also substitute for each other in this process. CD80 is rapidly induced on the surface of in vitro activated B cells, with Epstein Barr Virus (EBV) transformed B cell lines, with Burkitts lymphoma cell lines, with freshly isolated follicular B lymphoma cells, T cells, and monocytes. The B-lymphocyte activation antigen B7-1 provides regulatory signals for T lymphocytes as a consequence of binding to the CD28 and CTLA4 ligands of T cells. Diseases associated with CD80 dysfunction include gallbladder squamous cell carcinoma and myocarditis.
