Human IL-1RA ELISA Kit

Natural and recombinant human IL-1RA. There is no detectable cross-reactivity with other relevant proteins. Protein function: Inhibits 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. [The UniProt Consortium]
