W17233G_ULEAF_CD86_Block_032825 — Biotinylated recombinant human CTLA-4- Fc chimera (Cat. No. 786706) (black circles) binds to immobilized recombinant human B7-2/CD86-Fc chimera (Cat. No. 775606). Ultra-LEAF™ purified anti-human CD86 (clone W17233G) (purple squares) inhibits the binding in a dose-dependent manner, whereas the Ultra-LEAF™ purified rat IgG2b, κ Isotype Control (Cat. No. 400644) (gray triangles) does not have this effect. This antibody blocks the binding of 0.15 µg/mL biotinylated human CTLA-Fc chimera to 1 µg/mL immobilized recombinant human B7-2/CD86-Fc chimera. ND₅₀ range: 0.015 - 0.15 µg/mL.

Description

CD86, also known as B7-2, is a member of the cell surface immunoglobulin superfamily. B7 family members are transmembrane molecules that exist predominantly as monomers. They are classified into three groups according to their functions. Group I members include B7-1, B7-2, and B7-H2. These members are either co-stimulatory or co-inhibitory in modulating T cell response. Group II members include B7-H1 (PD-L1) and B7-DC (PD-L2) which are ligands for PD-1. These members are involved in regulating induction and maintenance of peripheral immune tolerance. Group III members include B7-H3 and B7-H4 whose role in T cell regulation has yet to be defined. CD86 is expressed on activated B and T cells, macrophages, dendritic cells, and astrocytes. CD86, along with CD80, is a ligand 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.

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?: BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
Does BioLegend test each Ultra-LEAF™ antibody by functional assay?: No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?: No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?: We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
