BAFF Receptor (BAFFR), a member of the TNFR superfamily, is highly expressed in the spleen, lymph nodes, 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. ?Human and mouse BAFF R share 56% aa sequence identity. BAFF R is highly expressed in spleen, lymph node and resting B?cells. It is also expressed at lower levels in activated B cell, in resting CD4+?T?cells, in thymus and peripheral blood leukocytes. BAFF knockout mice lack mature B cells. Similarly, A/WySnJ mice that are defective in BAFF-R intracellular signaling also lack mature B cells, suggesting that BAFF R is the critical receptor for BAFF during B lymphopoiesis. In contrast, BCMA BAFF Receptor (BAFFR), a member of the TNFR superfamily, is highly expressed in the spleen, lymph nodes, and resting B cells, and to some extent in activated B cells, resting CD4+ cells and peripheral blood leukocytes.

Similarly, A/WySnJ mice that are defective in BAFF-R intracellular signaling also lack mature B cells, suggesting that BAFF R is the critical receptor for BAFF during B lymphopoiesis. In contrast, BCMA- or TACI-deficient mice have no major defect in B-cell development. While the function of BCMA is not defined, TACI has been shown to control B-cell homeostasis and T-cell-independent immune responses. Product Properties Synonyms BAFFR, TNFRSF13C Accession Q96RJ3 GeneID 115650 Source E.coli-derived Human B cell Activating Factor Rececptor protein,Met1-Gly76,with an N-terminal Met Molecular Weight Approximately 7.8 kDa AA Sequence MRRGPRSLRG RDAPAPTPCV PAECFDLLVR HCVACGLLRT PRPKPAGASS PAPRTALQPQ ESVGAGAGEA ALPLPG Tag None Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 95% by SDS-PAGE and HPLC analyses. Biological Activity Fully biologically active when compared to standard. The ED50 as determined by its ability to block BAFF induced mouse splenocyte survival is 1.0-5.0 μg/ml in the presence of 1.0 μg/ml of rHuBAFF. Endotoxin < 1 EU/μg of protein as determined by LAL method. Formulation Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 8.0, 500 mM NaCl. Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions. Shipping and Storage The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles. Cautions 1. Avoid repeated freeze-thaw cycles. 2. For your safety and health, please wear lab coats and disposable gloves for operation. 3. For research use only. - or TACI-deficient mice have no major defect in B-cell development.
