B7-2/CD86 Protein, Human, Recombinant (hFc)

B7-1 and B7-2 are homologous costimulatory ligands expressed on the surface of antigen presenting cells (APCs) . Binding of these molecules to the T cell costimulatory receptors, CD28 and CTLA-4, is essential for the activation and regulation of T cell immunity. B7-1 and B7-2 do not form hetero-oligomers, underscoring the biological relevance of dimeric and monomeric state of B7-1 and B7-2, respectively. B7-2 Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with C-hFc tag. The predicted molecular weight is 52 kDa and the accession number is P42081-1.
