GRADE & PURITYCarrier 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

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

Recombinant Human BAFF/BLyS/TNFSF13B Protein (rp169674) - 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.
Recombinant Human BAFF/BLyS/TNFSF13B Protein (rp169674) - ELISA 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.
Recombinant Human BAFF/BLyS/TNFSF13B Protein (rp169674) - SDS-PAGE 3 μg/lane of Recombinant Human BAFF/BLyS/TNFSF13B Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 16.1 kDa under reducing conditions and 14.6 & 16.5 & 34.5 kDa under non-reducing conditions. TNFSF13B is a member of the tumor necrosis factor (TNF) superfamily ligand family. Proteins of this superfamily generally exert their functions as multimers (PMID: 18555199).
