FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: in vivo and in vitro blocking 1,4,5 of autoantibody production and T cell activation, stimulation of B cell activity3, immunoprecipitation2, and immunohistochemical staining2 of acetone-fixed frozen sections.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 1.0 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

LPS-stimulated (3 days) BALB/c splenocytes

LPS-stimulated (3 days) BALB/c splenocytes stained with PO3 PE


CD86 is an 80 kD 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. The PO3 antibody has been shown to block autoantibody production in vivo and inhibit T cell activation in vitro.
