CD6-H82F5-Cell-based assay
 B7-2 FACS

FACS analysis shows that the binding of Biotinylated Human B7-2, Fc,Avitag, premium grade (Cat. No. CD6-H82F5) to CD28 expressed on Jurkat E6.1 was inhibited by increasing concentration of neutralizing Anti-CD28 antibody. The concentration of B7-2 used is 1.5 μg/mL. The IC50 is 0.031 μg/mL (Routinely tested).

Synonym Name



Cluster of Differentiation 86 (CD86) is also known as B-lymphocyte activation antigen B7-2, is a type I membrane protein that is a member of the immunoglobulin superfamily, and is constitutively expressed on interdigitating dendritic cells, Langerhans cells, peripheral blood dendritic cells, memory B cells, and germinal center B cells. Additionally, B72 is expressed at low levels on monocytes and can be upregulated through interferon γ. CD86 is the ligand for two different proteins on the T cell surface: CD28 (for autoregulation and intercellular association) and CTLA-4 (for attenuation of regulation and cellular disassociation). CD86 works in tandem with CD80 to prime T cells. Recent study has revealed that B7-2 promotes the generation of a mature APC repertoire and promotes APC function and survival. Furthermore, the B7 proteins are also involved in innate immune responses by activating NF-κB-signaling pathway in macrophages. CD86 thus is regarded as a promising candidate for immune therapy. CD86+ macrophages in Hodgkin lymphoma patients are an independent marker for potential nonresponse to firstline-therapy.
