Recombinant Human BAFF Receptor/TNFRSF13C (Recombinant Human B Cell Activating Factor Receptor; rHuBAFF-R);重组人B细胞激活因子受体/TNFSF13C
Synonyms
BR3; CD268; TNFRSF13C
Purity
>95% by reduced SDS-PAGE 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 1.0-5.0μg/ml in the presence of 1.0μg/ml of rHuBAFF.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH8.0, 500mM NaCl.
Endotoxin
Less than 1EU/μg of rHuBAFF-R as determined by LAL method.
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 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background
B Cell Activating Factor Receptor (BAFF-R), also named tumor necrosis factor receptor superfamily member 13C, is a member of the TNFR superfamily. It 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. BAFF receptor is a type III transmembrane protein containing a single extracellular phenylalanine-rich domain and binds with high specificity to BAFF (TNFSF13B). It enhances B-cell survival in vitro and is a regulator of the peripheral B-cell population. BAFF receptor/BAFF signaling plays a critical role in B cell survival and maturation.
