Active Recombinant Human TNFSF13B, His-tagged, Animal Free

• Cat.No.: TNFSF13B-140H
• Product Overview: Recombinant human BAFF is a glycosylated polypeptide chain containing 151 amino acids (134-285 aa Q9Y275 (TN13B_HUMAN) fused to 10 His tag at N-terminal. rHuman BAFF has a molecular mass between 18 and 20kDa. Human recombinant protein expressed in Nicotiana benthamiana. Recombinant human B lymphocyte activating factor (BAFF) contains a 10-His-tag at the N-terminal end, is produced by transient expression in non-transgenic plants and is purified by sequential chromatography (FPLC). This product contains no animal–derived components or impurities. Animal free product.

Specification

• Description: BAFF (B lymphocyte activating factor) is a member of the tumor necrosis factor (TNF) ligand family which is expressed in T Cells, macrophages, monocytes and dendritic cells. It is also known as BLyS, THANK, TALL, zTNF4 and TNFS20. BAFF enhances B cell survival in vitro and has emerged as a key regulator of peripheric B cell and it is vital homeostatic cytokine for B cells that helps regulate both innate and adaptive immune responses. BAFF binds to three TNF receptors: B-cell maturation antigen (BCMA/TNFRSF17), transmembrane activator and calcium modulator and cyclophilin ligand interactor(TACI/TNFRSF13B) and BAFF receptor (BAFF R/BR3/TNFRSF 13C).The human BAFF gene code for a 285 amino acids type II transmembrane protein. Recombinant human soluble BAFF is a 151 amino acids containing the TNF-like portion of the extracellular domain of BAFF.
