BAFF

(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.

Activity
Measured by its binding ability in a functional ELISA. Immobilized TNFSF13B at 10 μg/ml can bind human BCMA (CSB-MP023974HU1), the EC₅₀ of human TNFSF13B protein is 221.3-298.6 ng/ml.

Human TNFSF13B protein Fc tag (CSB-MP897523HU1) captured on COOH chip can bind Human BCMA protein Fc tag (CSB-MP023974HU1) with an affinity constant of 39 nM as detected by LSPR Assay.

Activity
Measured by its binding ability in a functional ELISA. Immobilized TNFSF13B at 2 μg/ml can bind TNFRSF13C(CSB-MP853495HU1), the EC₅₀ is 9.943-15.72 ng/ml.

The purity of TNFSF13B was greater than 90% as determined by SEC-HPLC
