Ala 134 - Leu 285

A DNA sequence encoding the soluble form of human BAFF (Q9Y275-1) (Ala 134-Leu 285) was fused with the Fc region of human IgG1 at the N-terminus.

> 95 % as determined by SDS-PAGE

1. Measured by its binding ability in a functional ELISA. Immobilized recombinant human BAFF at 1 μg/mL (100 μl/well) can bind human TNFRSF17. The EC₅₀ of human TNFRSF17 is 0.07 μg/mL.
2. Measured in a cell proliferation assay using anti-IgM stimulated mouse splenic cells. The ED₅₀ for this effect is typically 50-150 ng/mL.

The recombinant human BAFF/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 389 amino acids and has a predicted molecular mass of 43.7 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhBAFF/Fc monomer is approximately 48-55 kDa due to glycosylation.

Tumor necrosis factor ligand superfamily member 13B

Cytokine that binds to TNFRSF13B/TACI and TNFRSF17/BCMA. TNFSF13/APRIL binds to the same 2 receptors. Together, they form a 2 ligands -2 receptors pathway involved in the stimulation of B- and T-cell function and the regulation of humoral immunity. A third B-cell specific BAFF-receptor (BAFFR/BR3) promotes the survival of mature B-cells and the B-cell response.

Lyophilized from sterile PBS, pH 7.4
1. 5 % trehalose and mannitol are added as protectants before lyophilization.
