| Introduction | Interleukin-22 （IL-22）, also known as IL-10-related T cell-derived inducible factor （IL-TIF） was initially identified as a gene induced by IL-9 in mouse T cells and mast cells. Mouse IL-22 cDNA encodes a 179 amino acid residue protein with a putative 33 amino acids signal peptide that is cleaved to generate a 147 aa mature protein that shares approximay 79% and 22% aa sequence identity with human IL-22 and IL-10, respectively. IL-22 has been shown to activate STAT-1 and STAT-3 in several hepatoma cell lines and upregulate the production of acute phase proteins. IL-22 is produced by normal mouse T cells upon Con A activation. Mouse IL-22 expression is also induced in various organs upon lipopolysaccharide injection, suggesting that IL-22 may be involved in inflammatory responses. The functional IL-22 receptor complex consists of two receptor subunits, IL-22R （previously an orphan receptor named CRF2-9） and IL-10R? （previously known as CRF2-4）, belonging to the class II cytokine receptor family. | |||
| Description | Interleukin-22 Mouse Recombinant produced in E.Coli is a single, non-glycosylated homodimeric polypeptide chain containing 147 amino acids and having a molecular mass of 16.7 kDa. The Murine IL-22 is purified by proprietary chromatographic techniques. | |||
| Source | Escherichia Coli. | |||
| Physical Appearance | Sterile Filtered White lyophilized （freeze-dried） powder. | |||
| Formulation | Lyophilized from 1X PBS. | |||
| Solubility | It is recommended to reconstitute the lyophilized Interleukin -22 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | |||
| Stability | Lyophilized Interleukin-22 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL22 should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles. | |||
| Purity | Greater than 97.0% as determined by（a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE. | |||
| Amino acid sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Met-Leu-Pro-Val-Asn. | |||
| Biological Activity | The ED50 as determined by its ability to induce IL-10 secretion in Colo205 cells is less than 0.5ng/ml, corresponding to a Specific Activity of 2,000,000IU/mg. | |||
