Active Recombinant Human TNFRSF1B, Fc Chimera

• Cat.No.: TNFRSF1B-165H
• Product Overview: Recombinant Human TNFRSF1B (Accession # AAA36755) was produced in Mouse myeloma cell line, NS0-derived.

Specification

• Species: Human
• Source: Mammalian Cells
• Tag: Fc
• Predicted N Terminal: Leu23
• Form: Lyophilized from a 0.2 µm filtered solution in PBS.
• Bio-activity: Measured by its ability to inhibit the TNF-alpha mediated cytotoxicity in the L-929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D. Matthews, N. and M.L. Neale (1987) in Lymphokines and Interferons, A Practical Approach. Clemens, M.J. et al. (eds): IRL Press. 221.The ED50 for this effect, in the presence of 0.25 ng/mL of TNF-alpha, is typically 0.004-0.016 µg/mL.
• Molecular Mass: Recombinant Human TNFRSF1B, Fc Chimera has a calculated MW of 52.6 kDa (monomer). In SDS-PAGE migrates as 70 kDa, reducing conditions.
• Purity: >95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
• Storage: Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at: In lyophilized state for 1 year (4ºC); After reconstitution under sterile conditions for 3 months (-70ºC).
