The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.1 - 1 µg/ml.
FunctionInhibits the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. Has no interleukin-1 like activity. Binds functional interleukin-1 receptor IL1R1 with greater affinity than decoy receptor IL1R2; however, the physiological relevance of the latter association is unsure.
Tissue specificityThe intracellular form of IL1RN is predominantly expressed in epithelial cells.
Involvement in diseaseMicrovascular complications of diabetes 4 Interleukin 1 receptor antagonist deficiency
