背景介绍 The B cell-activating factor from the TNF family (BAFF), is emerging as an important regulator of B cell and T cell responses. BAFF was originally identified as a factor responsible for B cell survival and maturation .BAFF binds to several receptors. These include transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI), BAFF-R (BR3), and B cell maturation Ag (BCMA). BAFF-R appears to be particularly important for the regulation of B cell survival and maturation in the spleen, because A/WySnJ mice expressing a defective BAFF-R have disrupted B cell maturation, similar to that seen in BAFF-deficient mice. 产品介绍 Recombinant human BAFF-R (B cell-activating factor from the TNF family), also known as CD268, is a disulfide-linked monomeric protein consisting of 76 a.a. and migrates as an approximately 9 kDa protein under reducing and non-reducing conditions. Optimized DNA sequence encoding human BAFF-R extracellular domain was expressed in E. coli.
