BAFF (TNFSF13B) plays a central role in B cell survival, maturation, and class-switch recombination, making it a critical tool for dissecting NF-κB signaling and B cell biology in cancer research. This recombinant human TNFSF13B (aa 134–285), expressed as an N-terminal hFc-tagged protein in mammalian cells, demonstrates confirmed binding to both BCMA (EC50 of 221.3–298.6 ng/ml) and BAFF-R/TNFRSF13C (EC50 of 9.943–15.72 ng/ml) in functional ELISA, supporting its use in receptor-ligand interaction studies, antibody blocking assays, and as a coating antigen for ELISA-based antibody screening. The validated dual-receptor engagement provides a suitable basis for B cell proliferation and survival assays, NF-κB pathway activation studies, and reference standard development in BAFF detection platforms. Purity exceeding 90% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for immune cell functional assays where LPS-driven artifacts must be excluded.

Review: We purchased Biotinylated human TNFSF13B, and verified that TNFSF13B-Biotin has good binding activity with BCMA through ELISA, and the EC50 was 0.1752-0.3657 ng/ml. It can be used for subsequent blocking ELISA experiments, and the experimental data is stable. We aliquoted and stored it properly, and it can maintain good activity after a long time!
