产品描述: 产品名称:Recombinant Mouse B7-1/CD80 (C-6His) 描述: Recombinant Mouse T-lymphocyte Activation Antigen CD80 is produced by our Mammalian expression system and the target gene encoding Val38-Asn246 is expressed with a 6His tag at the C-terminus. 氨基酸序列: VDEQLSKSVKDKVLLPCRYNSPHEDESEDRIYWQKHDKVVLSVIAGKLKVWPEYKNRTLYDNTTY SLIILGLVLSDRGTYSCVVQKKERGTYEVKHLALVKLSIKADFSTPNITESGNPSADTKRITCFA SGGFPKPRFSWLENGRELPGINTTISQDPESELYTISSQLDFNTTRNHTIKCLIKYGDAHVSEDF TWEKPPEDPPDSKNHHHHHH 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. Mouse CD80 consists of an extracellular domain (ECD) with twoimmunoglobulin-like domains, transmembrane segment, and cytoplasmic domain. 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. 别名: T-lymphocyte activation antigen CD80; Activation B7-1 antigen; B7; CD80 Accession: Q00609 纯度: Greater than 95% as determined by reducing SDS-PAGE. 来源: Human Cells 内毒素水平: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test. 溶解方法: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 形态: Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.
