CD86 (T-lymphocyte Activation Antigen CD86, Activation B7-2 Antigen, B70, BU63, CTLA-4 Counter-receptor B7.2, FUN-1, CD28LG2)

CD86 is an 80kD immunoglobulin superfamily member, also known as B7-2, B70, and Ly-58. CD86 is expressed on activated B and T cells, macrophages, dendritic cells and astrocytes. CD86 along with CD80 are the ligands of CD28 and CD152 (CTLA-4). CD86 is expressed earlier in the immune response than CD80. CD86 has also been shown to be involved in immunoglobulin class-switching and triggering of NK cell-mediated cytotoxicity. CD86 binds to CD28 to transduce co-stimulatory signals for T cell activation, proliferation, and cytokine production. CD86 can also bind to CD152, also known as CTLA-4, to deliver an inhibitory signal to T cells. This antibody can block the mixed lymphocyte reaction in vitro and has been shown to inhibit the priming of cytotoxic T lymphocytes in vivo (along with antibodies against B7-1).||Applications:|Suitable for use in Flow Cytometry, Immunohistochemistry, Immunofluorescence and Immunoprecipitation.
