DATA SHEET:   recombinant HUMAN INTERLEUKIN-22

-Interleukin-22 :Human IL-22 also known as T cell-derived inducible factor (ILTIF), is a cytokine that is structurally related to IL-10. Studies have shown that IL-22 induces acute-phase reactants in vitro and vivo. This sugests that this cytokine contributes to the regulation of inflammatory responses. This recombinant Human IL-22 is a 16.8 kDa protein consisting of 147 amino acid residues.

Supplied: Lyophilized powder from 10mM NaCitrate pH4.0

Source: E. Coli

Purity: >97% by SDS-Page analysis and HPLC analysis. Endotoxin level less than 0.1ng/ug (1EU/ug)

Reconstitution: We recommend a quick spin followed by reconstitution in 10nM NaCitrate pH 4.0 or sterile DI water to a concentration of 0.1-1.0 mg/ml. Allow to set at least 30 minutes at 4 DEG C, tighten cap and rotate to reconstitute any material on sides of vial. If desired, you can centrifuge at 1000 rpm for 1 minute to concentrate volume in bottom of vial. This solution can be diluted into other buffered solutions contaning carrier protein or medium containing serum and stored at 4 DEG C (up to 1 week) or -20 DEG C long   term)

Storage: The lyophilized powder is stable at room temperature for a few weeks but it is best stored desiccated at -20 Deg C. Reconstituted IL-22 should be stored in working aliquots at -20 DEG C . AVOID FREQUENT FREEZE THAW CYCLES.

Reactivity: not determined
