Product Overview
This rabbit polyclonal antibody detects interleukin-22 (gene IL22) in human, mouse and rat samples and is validated for ELISA, IHC and Western blot. The predicted molecular weight is 20.0 kDa, and the supplier reports an observed band at about 24 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 (Human, Mouse, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human, Mouse) |
| ELISA (capture antibody) | 1–5 µg/mL (Human) |
Samples with a confirmed band (WB): 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, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human rectum adenocarcinoma tissue, human spleen tissue, mouse thymus tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human IL-22 fragment (Ala34–Ile179), expressed in E. coli. Sequence identity with the mouse ortholog: 81.4%.
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.
