B7-2/CD86, also known as T-lymphocyte activation antigen CD86 isoform 1, is a variably glycosylated protein in the B7 family. These family members play important roles in immune activation and the maintenance of immune tolerance. It is expressed on antigen-presenting cells that provides co-stimulatory signals necessary for T cell activation and survival and exists predominantly as a monomer on cell surfaces. Also, it interacts with two co-stimulatory receptors CD28 and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) expressed on T cells that it induces the signal pathways which regulate T cell activation and tolerance, cytokine production, and the generation of CTL. Recombinant protein corresponding to aa31-247 from human B7-2/CD86, fused to His-Tag at C-terminal, expressed in Baculovirus.
