Storage, Stability and Shipping : Upon reconstitution, this cytokine can be stored in working aliquots at 2o - 8oC for one month, or at -20oC for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
Applications : Cell Assay
Endotoxin Level : <1.0 EU/μg of recombinant protein as determined by the LAL method.
Molecular Weight : 17.0 kDa
Gene Aliases : IL-22, IL-TIF, Cytokine Zcyto18, IL-10-related T cell-derived-inducible factor, ILTIF, ZCYTO18
Recombinant Human Interleukin-22 (IL22)
Reconstitution Protocol : A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Scientific Background : Originally identified as a gene induced by IL-9 in mouse T cells and mast cells, IL-22 is a member of the IL-10 family of cytokines. IL-22 inhibits IL-4 production by Th2 cells, and induces acute phase reactants in the pancreas and liver. The IL-22 receptor complex consists of two receptor subunits, IL-22R and IL-10R-beta that belong to the class II cytokine receptor family. Recombinant human IL-22 is a non-disulfide-linked homodimeric protein.
Sample Cell Assay Data : Activity was determined by the ability to inhibit growth of human A549 cancer cells at concentrations ranging between 50-100 ng/mL.
Purity : Recombinant Human IL22 resolved on a 15% SDS-PAGE gel under reducing conditions and stained with Coomassie Brilliant Blue G-250
