Tumor necrosis factor receptor superfamily, member 1A, (TNFRI) also known as TNFRSF1A or CD120A is the principal receptor through which many of the pro-inflammatory activities of TNF-alpha are mediated.1 TNFRI contains a death domain through which it interacts with other death-domain proteins to promote cellular responses.2 It regulates immune and inflammatory responses.3

N-terminal Sequence Analysis
State of Matter
Predicted Molecular Mass
The predicted molecular weight of Recombinant Mouse TNF RI is Mr 48.6 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is Mr 70 kDa.
This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.
Storage and Stability
This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
