简介
IL-1RN protein serves as an anti-inflammatory antagonist, targeting proinflammatory cytokines IL1B and IL1A within the interleukin-1 family. Playing a protective role, it prevents immune dysregulation and systemic inflammation induced by IL1, particularly in response to innate stimulatory agents. IL-1RN's regulatory activity contributes to a balanced immune response, safeguarding the host from the detrimental effects of excessive inflammation. IL-1RA/IL-1RN Protein, Mouse is the recombinant mouse-derived IL-1RA/IL-1RN protein, expressed by E. coli , with tag free.
- Application
-
Biological Activity
Measured by its ability to inhibit IL-1 alpha -dependent proliferation in CTLL-2 cells. The ED50 for this effect is ≤64.28 ng/mL in the presence of 50 pg/mL of recombinant human IL-1 alpha, corresponding to a specific activity is ≥1.56×104 units/mg.

Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Protein Description
Interleukin-1 receptor antagonist (IL-1RA) is a key regulatory protein in the interleukin-1 cytokine family, playing a crucial role in modulating inflammatory responses. IL-1 is known to contribute significantly to various pathological conditions, including autoimmune diseases, chronic inflammatory disorders, and even certain cancers. The delineation of its role has spurred interest in IL-1RA as a potential therapeutic agent. Recombinant IL-1RA, produced through recombinant DNA technology, has been extensively studied for its ability to antagonize the effects of IL-1 by binding to its receptors without eliciting a biological response. This mechanism makes IL-1RA a promising candidate for treating conditions characterized by excessive IL-1 activity. Clinical trials have demonstrated its efficacy in conditions such as rheumatoid arthritis and other inflammatory diseases. Moreover, ongoing research is exploring its potential application in a broader range of inflammatory and degenerative diseases, highlighting IL-1RA's significance in therapeutic strategies aimed at restoring immune homeostasis and mitigating disease progression. The exploration of IL-1RA as a treatment provides hope for patients suffering from debilitating conditions driven by chronic inflammation.
