Optimized DNA sequence encoding extracellular domain of mouse Interleukin-31 receptor beta subunit (OSM-Rb) including a C-terminal tag was expressed in HEK293 cells.
Recombinant mouse IL-31RB is a monomer protein consisting of 725 amino acid residue subunits, due to glycosylation migrates as an approximately130 kDa protein on SDS-PAGE.
>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 IL-31RB (OSM-R) is supplied as a 0.2 μm filtered PBS solution, pH7.2 .
Recombinant mouse IL-31 receptor beta, as supplied, 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.
