Optimized DNA sequence encoding extracellular domain of Mouse TNF receptor type 1 (TNFR1) including a C-terminal 6His tag was expressed in HEK293 cells.
Recombinant Mouse TNF receptor 1 (CD120a) is a protein consisting of 201 amino acid residue subunits, due to glycosylation migrates as an approximately 35kDa protein on SDS-PAGE.
>95%, as determined by SDS-PAGE and HPLC
Recombinant Mouse TNF receptor 1 (CD120a) activity was determined by the ability to inhibit the TNFα mediated cytotoxicity in the L929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D.
The ED50 for this effect is typically 0.5-1.5 μg/mL in the presence of 0.15 ng/mL recombinant mouse TNFα .
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Recombinant Mouse TNFR1 (TNFRSF1A) is supplied as a 0.2 μm filtered PBS solution, pH7.2.
Recombinant Mousen TNF receptor 1 (CD120a), as supplied, can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.
Avoid repeated freeze/thaw cycles.

The effects of TNFα are
mediated by two distinct
cell surface receptors, p55
TNF-R1 and p75 TNF-R2, that
are expressed on almost all
nucleated cells. Both
receptors lack recognizable
enzymatic domains, and their
ability to transduce signals
is dependent on the

receptor 1 (TNF-R1) lacks
intrinsic signaling capacity
and transduces signals by
molecules. The TNF-R1
associated death domain
protein interacts with the
