Optimized DNA sequence  encoding extracellular domain of Mouse  IL-18 receptor  including an C terminal IgG1 Fc  tag was expressed in HEK293 cells.

Molecular weight:

Recombinant mouse IL-18 receptor alpha is a homodimer protein consisting of two 555 amino acid residue subunits,  due to glycosylation migrates as an approximately 95kD protein under reducing  SDS-PAGE conditions.

>98%, as determined by SDS-PAGE and HPLC
Biological Activity:
Measured by its ability to bind immobilized recombinant human IL-18 at a concentration range of 1-32ng/ml in a functional ELISA assay.
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 Interleukin-18 receptor alpha  is supplied as lyophilized 0.2 μm filtered PBS solution,  pH7.2 .

Recombinant IL-18 receptor alpha, 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.

IL-18 receptor

The IL-18R complex is composed of two known chains, IL-18 receptor α chain (IL-18Rα)and IL-18Rβ. IL-18Rα (IL-1R5) was originally described as IL-1 receptor-related protein (IL-1Rrp) because of its homology with the IL-1/Toll receptor family and is the extracellular binding domain of the IL-18R complex. IL- 18Rβ (also known as IL- 18RAcPL or IL-1R7) is the signal transducing chain of the IL-18R complex and is also a member of the IL-1R family. It has been widely believed that the IL-18Rα is not expressed on naive T cells, but is induced during differentiation of Th1, but not Th2, cells.
