产品名称：Recombinant Human B7-1/CD80 (C-6His)

描述: Recombinant Human Activation B7-1 antigen is produced by our Mammalian expression system and the target gene encoding Val35-Asn242 is expressed with a 6His tag at the C-terminus.

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. It is the ligand for two different proteins on the T cell surface: CD28 and CTLA-4. Studies have shown that CTLA-4 binds mostly to CD80. The structure presents two extracellular domains: a membrane distal variable-like domain (IgV) and a membrane proximal Ig constant-like domain (IgC) along with an intracellular domain. Both IgV and IgC consist of anti-parallel beta sandwiches joined by a short linker region. CD80 is mostly expressed on the surface of antigen-presenting cells including activated B cells, macrophages and dendritic cells.

别名: CD80, Activation B7-1 antigen, B7, BB1, CD28LG1, CD28LGB7-1 antigen, T-lymphocyte activation antigen CD80

Accession: P33681

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, pH 7.4.
