Description
IL-22 is a member of the 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, IL-22 inhibits IL-4 production by Th2 cells, and induces acute phase reactants in the liver and pancreas. IL-22 signals through a receptor system consisting of IL-10R-ß/CRF2-4 and IL-22R, both of which are members of the class II cytokine-receptor family.
M.W.
Approximately 33.6 kDa, non-disulfide-linked homodimeric protein containing of two 147 amino acid polypeptide chains.
Purity
>97% by SDS-PAGE and HPLC analyses.
Endotoxin Level
Less than 0.2EU/ug of rHuIL-22 as determined by LAL method.
Specific Activity
Fully biologically active when compared to standard. The ED50 determined by inducing IL-10 secretion of human COLO 205 cells is less than 0.3 ng/ml, corresponding to a specific activity of >, 3.3 x 106 IU/mg.
Storage
This lyophilized preparation is stable at 2-8 C, but should be kept at -20 C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 C to -70 C. Avoid repeated freeze/thaw cycles.
Formulation
Lyophilized from a 0.2µ, m filtered concentrated, solution in PBS, pH 6.0.
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.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Usage
This material is for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
