Description:
BAFF (B lymphocyte activating factor) is a member of the tumour 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 periphery 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.

Applications:
Functional studies, Cell culture, Western Blot.
Bioassay 1 - Result assay 1:
The activity is determined by dose-dependent response of proliferation Anti IgG M stimulated B cell from Human PBMC. Cell proliferation was measured by MTT method. *activity results may vary with PBMC donors. - The ED50 for this effect is typically <10ng/ml in presence of goat anti-human IgM (u chain specific).
