Background

IL (interleukin)-22 is an IL-10 homologue, produced by activated T cells that binds to and signals via the class II cytokine receptor (R) heterodimer IL-22RA1/CFR2-4 (IL-10R2).1 IL-22 regulates the production of acute phase proteins of the immunological response. On binding to its cognate receptor (IL-22R1), which is associated to the interleukin-10 receptor 2, IL-22 promotes activation of signal transducer and activator of transcription (STAT) pathway and several other cellular responses.2 IL-22 plays an important role in skin inflammatory processes and wound healing.3

Protein Details

Purity
>95% by SDS Page and analyzed by silver stain.
Endotoxin Level
<1.0 EU/µg as determined by the LAL method
Biological Activity
The biological activity of Human IL-22 was determined by its ability to induce IL-10 secretion in Colo205 cells (Nagalakshmi, M.L. et al., 2004, International Immunopharmacology. 4:679-691 The expected ED50 for this effect is typically 60-300 pg/mL.
Expression Host
E. coli
Protein Accession No.
Amino Acid Sequence
The DNA sequence encoding the mature human IL-22 protein sequence (Ala 34 - Ile 179) was inserted into a suitable expression vector and was expressed in E coli (Dumoutier, L. et al., 2000, PNAS 97:10144).
State of Matter
Lyophilized
Predicted Molecular Mass
The predicted molecular weight of Recombinant Human IL-22 is Mr 16.5 kDa.
Formulation
This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.
Storage and Stability
This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
