Product Details
- Molecular Aliases
- CD268; BAFFR; BR3; TNFRSF13C; BROMIX; CVID4; prolixin
- Protein Length
- Ser7-Ala71
- Expression System

- Purity
- > 95% as determined by Bis-Tris PAGE
- Endotoxin
- Less than 1 EU per μg by the LAL method.
- Buffer / Formulation
- Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
- State
- Lyophilized
- Storage Conditions
- -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
- Reconstitution Advice
- Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

Background
BAFFR is an atypical representative of the TNF-receptor super-family. BAFFR [BAFFR = B cell activating f actor of the TNF-f amily receptor; a.k.a. BR3, Bcmd] expression starts when the immature B cells develop to transitional B cells, which then receive BAFFR-dependent pro-survival signals to rescue them from premature cell death. At protein level, the BAFFR is expressed on the surface of all human peripheral B cell subsets except for plasma cells and for centroblasts located in the dark zone of germinal centers. Its expression is upregulated after the expression of functional B cell antigen receptors (BCR) in response to tonic BCR signaling, which enhances BAFFR expression by immature and transitional B cells
