Optimized DNA sequence encoding Human extracellular domain of rat IL-1 receptor type 1 including a C-terminal His tag was expressed in HEK293 cells.
Recombinant IL-R1 (CD121a) is a protein consisting of 330 amino acid residue subunits, due to glycosylation migrates as an approximately 55-60 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 rat IL-1R (CD121a) is lyophilized from 0.2 μm filtered PBS solution, pH7.2 , 5% Trehalose.
Recombinant rat IL-1 receptor type 1 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.
