Applications
  •  
    Recommended
    Concentration
    Sample
  • Western Blot
    1 µg/mL
    Recombinant Mouse B7‑2/CD86 Fc Chimera (Catalog # 741-B2)
  • Flow Cytometry
    2.5 µg/106 cells
    Mouse splenocytes
  • CyTOF-ready
    Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
  • Neutralization
    Measured by its ability to neutralize B7‑2/CD86-induced IL‑2 secretion in the Jurkat human acute T cell leukemia cell line. Linsley, P. et al. (1990) Proc. Natl. Acad. Sci. 87:5031. The Neutralization Dose (ND50) is typically 0.05-0.25 µg/mL in the presence of 0.5 µg/mL Recombinant Mouse B7‑2/CD86 Fc Chimera and 10 µg/mL PHA.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Examples
IL‑2 secretion Induced by B7‑2/CD86 and Neutralization by Mouse B7‑2/CD86 Antibody. Recombinant Mouse B7‑2/CD86 Fc Chimera (Catalog # 741-B2) co-stimulates IL‑2 secretion in the Jurkat human acute T cell leukemia cell line in the presence of PHA in a dose-dependent manner (orange line), as measured by the Human IL‑2 Quantikine ELISA Kit (Catalog # D2050). IL‑2 secretion elicited by Recombinant Mouse B7‑2/CD86 Fc Chimera (0.5 µg/mL) and PHA (10 µg/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse B7‑2/CD86 Monoclonal Antibody (Catalog # MAB741). The ND50 is typically 0.05‑0.25 µg/mL.

Background: B7-2/CD86

B7-1 and B7-2, together with their receptors CD28 and CTLA-4, constitute one of the dominant costimulatory pathways that regulate T- and B-cell responses. Although both CTLA-4 and CD28 can bind to the same ligands, CTLA-4 binds to B7-1 and B7-2 with a 20‑100 fold higher affinity than CD28 and is involved in the down‑regulation of the immune response. B7-1 is expressed on activated B cells, activated T cells, and macrophages. B7-2 is constitutively expressed on interdigitating dendritic cells, Langerhans cells, peripheral blood dendritic cells, memory B cells, and germinal center B cells. Additionally, B7-2 is expressed at low levels on monocytes and can be up‑regulated through interferon gamma. B7-1 and B7-2 are both members of the immunoglobulin superfamily. Mouse B7-2 is a 309 amino acid (aa) protein containing a putative 23 aa signal peptide, a 221 aa extracellular domain, a 21 aa transmembrane domain, and a 44 aa cytoplasmic domain. Mouse B7-2 and B7-1 share 28% amino acid identity. Mouse and human B7-2 share 50% amino acid identity. However, it has been observed that both human and mouse B7‑1 and B7‑2 can bind to either human or mouse CD28 and CTLA-4, suggesting that there are conserved amino acids which form the B7-1/B7-2/CD28/CTLA-4 critical binding sites.
