TNFRSF1A Protein (C-human IgG1-Fc, Rat)

1. Measured by its ability to inhibit TNFα-mediated cytotoxicity in L-929 mouse fibroblast cells in the presence of metabolic inhibitor actinomycin D. The ED50 for this effect is typically 3-30 ng/mL in the presence of 0.05 ng/mL of ratTNFα. 2. Immobilized mouse TNFa (80-235) (Cat:50349-MNAE) at 10 μg/ml (100 μl/well) can bind rat TNFRSF1A-Fc, The EC50 of rat TNFRSF1A-Fc is 0.08-0.20 μg/ml.

The recombinant rat TNFRSF1A/Fc is a disulfide-linked homodimer. The reduced monomer comprises 431 amino acids and has a predicted molecular mass of 47.9 kDa. The apparent molecular mass of the protein is approximately 59 kDa in SDS-PAGE under reducing conditions.
