IL-22 Antagonist Mouse

Data sheet

Formulation

IL-22 Antagonist Mouse is lyophilized from a concentrated (1mg/ml) solution in water containing NaHCO3.

Solubility

It is recommended to reconstitute the lyophilized Interleukin -22 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 98.0% as determined by:(a) Gel filtration chromatography under non-denaturing conditions.(b) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.

Description

Interleukin-22 Antagonist Mouse Recombinant produced in E.Coli is a single, non-glycosylated homodimeric polypeptide chain containing 147 amino acids and having a total molecular mass of 16.7 KDa. The Mouse IL-22 Antagonist is purified by proprietary chro

Protein Background

IL-22 is a member of the IL-10 family of regulatory cytokines.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

Expression host

Escherichia Coli.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized Interleukin-22 Mouse Antagonist although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL22 Antagonist should be stored at 4°C between 2-7 days and for future use below -18°C.Please preven

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

IL-22 E117A mutant is capable of full inhibition of STAT3 phosphorylation induced by mouse interleukin 22 in HepG cells. Its affinity toward immobilized mIL-22 receptor a1 extracellular domain (mIL-22 Ra1-ECD) or IL-22 binding protein is similar to the no
