IL 1RA Rat

Data sheet

Formulation

Lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4.

Solubility

It is recommended to reconstitute the lyophilized IL 1RA in sterile 18M?-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 95.0% as determined by SDS-PAGE.

Description

IL 1RA Rat Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 152 amino acids and having a molecular mass of 17.5kDa.The IL 1RA Rat is purified by proprietary chromatographic techniques.

Protein Background

Interleukin-1 ra is a member of the interleukin 1 cytokine family. This protein inhibits the activities of interleukin 1, alpha (IL1A) and interleukin 1, beta (IL1B), and modulates a variety of interleukin 1 related immune and inflammatory responses. This

Expression host

Escherichia Coli.

Synonyms

IRAP, IL1F3, IL1RA, IL-1ra3, ICIL-1RA, IL1RN, IL1 inhibitor, IL-1ra, MGC10430.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized IL 1RA although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL 1RA should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.
