Product Description	Recombinant Human BAFF/TNFSF13B/CD257 Trimer Protein is expressed from HEK293 with monomeric hFc tag and Flag tag at the N-Terminus.It contains Thr141-Leu285 trimer design.
Product Background	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 TNFSF13B gene.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/BAFF-R.
