Biological Activity
The ED50 was determined by its ability to activate STAT following receptor ligand interaction and found to be <5ng/ml, corresponding to a specific activity of 200,000 units.

Description
IL-31 human recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 141 amino acids (24-164 a.a.) and having a molecular mass of 15.8 kDa.

The IL-31 (1mg/ml) was lyophilized with 20mM Phosphate buffer, 150mM NaCl pH-7.4.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Purity
Greater than 95.0% as determined by(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized IL-31 in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
Escherichia Coli.

Stability
Lyophilized IL-31 Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution IL-31 should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
Please prevent freeze-thaw cycles.

Synonyms
Interleukin 31, IL31, IL-31.
