| Purity |
> 96 % by SDS-PAGE and HPLC analyses. |
| Biological Activity |
Fully biologically active when compared to standard. The ED50 as determined by inducing IL-10 secretion of human COLO 205 cells is less than 0.2 ng/ml, corresponding to a specific activity of > 5.0 × 106 IU/mg. |
| Physical Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation |
Lyophilized from a 0.2 μm filtered concentrated solution in 1 × PBS, pH 7.4. |
| Endotoxin |
Less than 1 EU/μg of rMuIL-22 as determined by LAL method. |
| Reconstitution |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions. |
| Stability & Storage |
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
- 12 months from date of receipt, -20 to -70 °C as supplied.
- 1 month, 2 to 8 °C under sterile conditions after reconstitution.
- 3 months, -20 to -70 °C under sterile conditions after reconstitution. |
| Usage |
This material is offered by Korea Lugen Sci for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. |

| Background |
IL-22 is belonging to IL-10 family of regulatory cytokines which includes IL-10, IL-19, IL-20, IL-22, IL-24 and IL-26. Members of this family share partial homology in their amino acid sequences, but they are dissimilar in their biological functions. Produced by T lymphocytes and dendritic cells, IL-10 contributes to the inflammatory response in vivo. IL-22 signals through CRF2-4 and IL-22. It along with IL-17 is rapidly produced by splenic LTi-like cells and can be also produced by Th17 cells. IL-22 likely plays a role in the coordinated response of both adaptive and innate immune systems. Recombinant mouse interleukin-22 contains 147 amino acids and it has approximately 81 % and 92 % amino acid sequence identity with human and rat IL-22. |
