Description
IL22RA (Y51A) Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 147 amino acids and having a molecular mass of 16.7 kDa. IL22RA (Y51A) is purified by proprietary chromatographic techniques.
Source
Escherichia coli.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
The protein was lyophilized from a concentrated (1mg/ml) solution with NaHCO3.
Solubility
It is recommended to reconstitute the lyophilized IL22RA (Y51A) in sterile 18MΩ-cm not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized IL22RA (Y51A) although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL22RA (Y51A) should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Purity
Greater than 98.0% as determined by:
(a) Gel filtration chromatography.
(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 Ala-Leu-Pro-Val-Asn.
Biological Activity
IL22RA (Y51A) Is capable of full inhibition of STAT3 phosphorylation induced by mouse interleukin 22 in HepG cells. Its affinity toward immobilized mIL-22 receptor α1 extracellular domain (mIL-22 Rα1-ECD) or IL-22 binding protein is similar to the non-mutated mouse interleukin 22. Mouse IL-22 antagonist (Y51A) has no agonistic activity in this bioassay.
Protein content
Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.18 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the DNAman computer analysis program of protein sequences.

Background
IL-22 belongs to the IL-10 family of regulatory cytokines and produced by several populations of immune cells at a site of inflammation. Members of this family share partial homology in their amino acid sequences, but varies in their biological functions. IL-22 takes effect on non-hematopoietic cells. IL-22 takes pat in wound healing and in protection against microbs.Produced by T lymphocytes, IL-22 inhibits IL-4 production by Th2 cells, and induces acute phase reactants in the pancreas and liver.
