IL-1RA/IL-1RN Protein, Rat (His)

Customer Review

Based on 1 Customer Validation

IL-1RA/IL-1RN mutant proteins are potent anti-inflammatory antagonists of the interleukin 1 family, specifically targeting the proinflammatory cytokines IL1B and IL1A. This mutant variant is designed for enhanced suppressive capacity, tightly protecting the host from immune dysregulation and preventing IL1 from triggering uncontrolled systemic inflammation in response to innate stimulators. IL-1RA/IL-1RN Protein, Rat (His) is the recombinant rat-derived IL-1RA/IL-1RN protein, expressed by E. coli , with C-6*His labeled tag.

Biological Activity

Description

IL-1RA/IL-1RN mutant proteins are potent anti-inflammatory antagonists of the interleukin 1 family, specifically targeting the proinflammatory cytokines IL1B and IL1A. This mutant variant is designed for enhanced suppressive capacity, tightly protecting the host from immune dysregulation and preventing IL1 from triggering uncontrolled systemic inflammation in response to innate stimulators. IL-1RA/IL-1RN Protein, Rat (His) is the recombinant rat-derived IL-1RA/IL-1RN protein, expressed by E. coli , with C-6*His labeled tag.

Background

The IL-1RA/IL-1RN mutant protein functions as a potent anti-inflammatory antagonist within the interleukin-1 family, specifically targeting proinflammatory cytokines like interleukin-1beta/IL1B and interleukin-1alpha/IL1A. Engineered to enhance its inhibitory capabilities, this mutant variant plays a critical role in safeguarding the host from immune dysregulation and preventing uncontrolled systemic inflammation triggered by IL1 in response to various innate stimulatory agents, including pathogens. By offering an optimized defense against IL1-mediated inflammatory responses, the mutant protein contributes significantly to maintaining immune balance and preventing excessive inflammation.

Verified Bioactivity

Measured by its ability to inhibit proliferation in CTLL‑2 mouse cytotoxic T cells in the presence of 50 pg/mL of rhIL-1 alpha. The ED50 for this effect is 84.78 ng/mL, corresponding to a specific activity is 1.180×104 units/mg.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
