FACS assay shows that recombinant Biotinylated FACS

Flow Cytometry assay shows that Biotinylated Human B7-2, Fc,Avitag (Cat. No. CD6-H82F5) can bind to CD28 expressed on Jurkat E6.1 cells. The concentration of B7-2 used is 1.5 μg/mL (Routinely tested).

CD6-H82F5-Cell-based assay
FACS assay shows that recombinant Biotinylated FACS

FACS analysis shows that the binding of Biotinylated Human B7-2, Fc,Avitag 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).


Loaded Cynomolgus / Rhesus macaque B7-2, Fc Tag (Cat. No. CD6-C5254) on Protein A Biosensor, can bind Human / Cynomolgus / Rhesus macaque CD28, His Tag (Cat. No. CD8-H52Hc) with an affinity constant of 11 μM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).


Loaded Human / Cynomolgus / Rhesus macaque CD28, Fc Tag (HPLC-verified) (Cat. No. CD8-H525a) on Protein A Biosensor, can bind Human B7-2, His Tag (Cat. No. CD6-H5223) with an affinity constant of 6.8 μM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).

B7-2 Molecule Synonym Name


B7-2 Molecule Background

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 ¦Ã. 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-¦ÊB-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.
