Tumor Necrosis Factor (Ligand) Superfamily Member 13B (TNFSF13B), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in analysis of protein structure, and performing cell based assays. It can also be used as an immunogen, as a protein standard, or in other research applications

This recombinant protein was expressed from a DNA sequence encoding the soluble form of human TNFSF13B (Q9Y275-1) (Ala 134-Leu 285).

Activity: Measured in a cell proliferation assay using anti-IgM stimulated mouse B cells. The ED₅₀ for this effect is typically 0.4-2 ng/ml in the presence of goat anti-mouse IgM µ chain.

Formulation: Lyophilized in 140 mM NaCl, 2.7 mM KCl, 10 mM Na₂HPO₄, 1.8 mM KH₂PO₄, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween 80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 25 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.
