Optimized DNA sequence encoding Mouse 4-1BB (CD137) fused to a C terminal IgG1 Fc tag was expressed in CHO Cells.
Recombinant Mouse 4-1BB (CD137) is a homodimer protein consisting of two 430 amino acid residue subunits, due to glycosylation migrates as an approximately 65kDa protein on SDS-PAGE under reducing conditions.
>97%, as determined by SDS-PAGE and HPLC
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 CD137 is lyophilized from 0.2 μm filtered PBS solution, pH7.2 .
Recombinant Mouse 4-1BB 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.

4-1BB (CD137) is a member of
the TNF receptor superfamily
expressed on activated CD4
and CD8 T cells as well as
on activated NK cells. The
binding of 4-1BB to its TNF
family ligand, 4-1BB ligand
(4-1BBL) delivers a
costimulatory signal to
resting T cells leading to
high level IL-2 production
