产品描述：

产品名称：Recombinant Rat T-lymphocyte Activation Antigen CD80/B7-1 (C-6His)

背景说明: Cluster of Differentiation 80, also called B7-1, is a member of cell surface immunoglobulin superfamily which plays key, yet distinct roles in the activation of T cells. B7-1/CD80 and B7-2/CD86, together with their receptors CD28 and CTLA4, constitute one of the dominant co-stimulatory pathways that regulate T- and B- cell responses. CD80 is mostly expressed on the surface of antigen-presenting cells including activated B cells, macrophages and dendritic cells. 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.

描述: Recombinant Rat T-lymphocyte Activation Antigen CD81 is produced by our Mammalian expression system and the target gene encoding Vla30-Gln248 is expressed with a 6His tag at the C-terminus.
