Product Overview
This rabbit polyclonal antibody detects interleukin-22 (gene IL22) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 20.0 kDa, and the supplier reports an observed band at about 20 kDa.
Interleukin-22 (IL-22) is an IL-10 family cytokine produced by immune cells such as Th17, Th22 and innate lymphoid cells, yet it acts mainly on epithelial and other non-immune cells. Through IL-22R1 and IL-10R2 it activates JAK1/TYK2 and STAT3, promoting epithelial survival, regeneration and barrier defense in gut, skin and lung.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|
Samples with a confirmed band (WB): human HeLa cells, human placenta tissue, rat thymus tissue, mouse thymus tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Immunogen
Synthetic peptide from the C-terminal region of human IL22. Sequence identity with the mouse and rat orthologs: 85.4% and 82.9%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes interleukin-22 as a secreted protein. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
