Sandwich ELISA quantitative detection kit for Mouse BAFF in cell culture supernates, serum and plasma (heparin, EDTA). B-cell activating factor (BAFF) also known as tumor necrosis factor ligand superfamily member 13B is a protein that in humans is encoded by the TNFLSF13B gene.1,2 BAFF is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for receptors TNFRSF13B/TACI, TNFRSF17/BCMA, and TNFRSF13C/BAFFR. This cytokine is expressed in B cell lineage cells, and acts as a potent B cell activator. It has been also shown to play an important role in the proliferation and differentiation of B cells.3All these ligands act as heterotrimers (i.e. three of the same molecule) interacting with heterotrimeric receptors4, although BAFF has been known to be active as either a hetero- or homotrimer.5 The standard used in this kit is recombinant mouse soluble BAFF (A127-L309) with molecular weight 23.2kD. Assay Range: 46.9pg/ml-3000pg/ml Sensitivity: < 10
