| Description | B7-2, also known as CD86, B70, and ETC-1, is a 60-100 kDa variably glycosylated protein in the B7 family. B7 family members are transmembrane cell surface molecules that play important roles in immune activation and the maintenance of immune tolerance B7-2 exists predominantly as a monomer on cell surfaces and interacts with two co-stimulatory receptors CD28 and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) expressed on T cells, and thus induces the signal pathways which regulate T cell activation and tolerance, cytokine production, and the generation of CTL. It is indicated that contacts between B and T helper cells mediated by CD86 encourage signals for the proliferation and IgG secretion of normal B cells and B cell lymphomas. B7-2 promotes the stabilization of CD28 in the IS, while The relative participation of B7-1 and B7-2 in T cell co-stimulation can also alter the Th1/Th2 bias of the immune response. Both B7-1 and B7-2 serve as cellular receptors for B species adenoviruses
Recombinant Human B7-2/CD86 produced in HEK293 cells is a polypeptide chain containing 228 amino acids with C-terminal 6His. A fully biologically active molecule, rhB7-2/CD86 has a molecular mass of 45-55 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript. |
