一般描述
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.
外形
Lyophilized from a 20 mM PBS buffer at pH 7 and 0.2 M NaCl.
重悬
Lyophilized protein should be reconstituted in water to a concentration of 25 - 50 ng /μl. Due to the protein nature, dimmers and multimers may be observed.
分析说明
The activity is determined by dose-dependeant stimulation of proliferation B cell from Human PBMC. Cell proliferation was measured by MTT method.
*activity results may vary with PBMC donors.

B-cell survival and differentiation critically depend on the interaction of BAFF-R and TACI with their ligands, BAFF and APRIL. Mature B-cell defects lead to Common Variable Immunodeficiency (CVID), which is associated with elevated serum levels of BAFF and APRIL. Nevertheless

B cell activating factor belonging to the TNF family (BAFF) is vital for B cell survival, proliferation and activation. Evidence indicates that BAFF is systemically or locally increased in glomerulonephritis (e.g. lupus nephritis, IgA nephropathy). However, the effect of BAFF

B-cell activating factor receptor (BAFF-R) is expressed on precursor B acute lymphoblastic leukemia (pre-B ALL) cells, but not on their pre-B normal counterparts. Thus, selective killing of ALL cells is possible by targeting this receptor. Here, we have further examined
