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°Cfor twelve months. Avoid repeated freeze/thaw cycles.
