Recombinant Human BAFF/BLyS/TNFSF13B Protein

Cat. No.: rp169674
AVAILABLE TO ORDER
GRADE & PURITY Carrier Free ? Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays. Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. High Performance ? High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short. PBS Only ? PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers. ≥90%(SDS-PAGE) See COA

Expression system
E. coli
Endotoxin Concentration
<1.0 EU/μg
Bioactivity
Measured in a cell proliferation assay using anti-IgM (115-006-020) stimulated mouse B cells. The ED50 for this effect is 0.78 ng/mL in the presence of 800 ng/mL anti-IgM. Immobilized Recombinant Human BAFF/BLyS/TNFSF13B Protein (rp169674) at 1.0 μg/mL can bind BAFF Antibody (Ab090522) with the EC50 of 346.4 ng/mL.

Biochemical and Physiological Mechanisms
B-cell activating factor (BAFF), also known as BLyS, TALL-1, THANK, and TNFSF13B, is a 32 kDa transmembrane glycoprotein in the TNF ligand superfamily. It is involved in multiple aspects of immune system regulation, particularly towards B cells. Mature hu
