BAFF Receptor (BAFFR), a member of the TNFR superfamily, is highly expressed in spleen, lymph node, and resting B cells and to some extent in activated B cells, resting CD4+ cells and peripheral blood leukocytes. BAFFR is a type III transmembrane protein that binds with high specificity to BAFF (TNFSF13B). BAFFR/BAFF signaling plays a critical role in B cell survival and maturation. Recombinant human BAFFR is a 76 amino acid polypeptide (7.7 kDa) corresponding to the extracellular portion of the full BAFFR protein.
Catalog #:
310-13R
Source :
E.coli
Purity :
Greater than 95% by SDS-PAGE gel and HPLC analyses
Endotoxin Level :
Endotoxin level is less than 0.1 ng per μg (1EU/μg)
Biological Activity :
Determined by its ability to block BAFF induced mouse splenocyte survival. The expected ED50 for this effect is 2.0-4.0 μg/ml in the presence of 1.0μg/ml of human soluble BAFF.
