|Product Overview:||Recombinant Cynomolgus Monkey CD80(Val35-Asn242) fused with His tag at C-terminal was expressed in HEK293.|
|Description:||B7-1/CD80 and B7-2/CD86, together with their receptors CD28 and CTLA-4, constitute one of the dominant co-stimulatory 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. Mature cynomolgus B7-1 consists of a 208 aa extracellular domain (ECD) with two immunoglobulin-like domains, a 21 aa transmembrane domain, and a 25 aa cytoplasmic domain. Within the ECD, cynomolgus B7-1 shares 97%, 51%, and 54% aa sequence identity with human, mouse, and rat B7-1, respectively. Both human and mouse B7-1 and B7-2 can bind to either human or mouse CD28 and CTLA-4. 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.|
|Predicted N Terminal:||Val35|
|Form:||Lyophilized from a 0.2 μm filtered solution in PBS.|
|Bio-activity:||Measured by its binding ability in a functional ELISA. When Recombinant Cynomolgus Monkey B7-1/CD80 is immobilized at 0.5 µg/mL (100 µL/well), the concentration of Recombinant Human CTLA-4 Fc Chimera that produces 50% of the optimal binding response is approximately 5-30 ng/mL.|
