| Description : |
Beta chain of interleukin-18 receptor (IL-18Rbeta) is an accessory protein-like molecule that is required for signaling IL-18 signals through its specific cell surface receptor IL-18R, which comprises two subunits: IL-18Rα and IL-18Rβ. IL-18Rα alone has a weak affinity for IL-18 binding, while the IL-18Rα/β complex has a high affinity. IL-18 Rβ is detected in numerous tissues including lung, spleen, leukocytes and colon. |
| Molecular Weight : |
The predicted molecular weight of Recombinant Human IL-18 Rβ is Mr 65.1 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 90-100 kDa. |
| Source : |
Mammalian cells |
| State Of Matter : |
Lyophilized. |
| Purity : |
>90% by SDS Page and analyzed by silver stain. |
| Endotoxin : |
<1.0 EU/µg as determined by the LAL method. |
| Biological Activity : |
The biological activity of Human IL-18 Rβ was determined byits ability to inhibit IL-18 induced response on KG-1 cells, in the presence of soluble IL-18 Rα/Fc. The expected ED50 for this effect is typically 2 - 6 μg/mL in the presence of 30 μg/mL of soluble IL-18 Rα/Fc and 40 ng/mL of human IL-18. |
| Storage And Stability : |
This lyophilized protein is stable for six to twelve months when stored desiccated at -20℃ to -70℃. After aseptic reconstitution, this protein may be stored at 2℃ to 8℃ for one month or at -20℃ to -70℃ in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions. |
