IL-22 (Ala34-Ile179)
Accession # Q9GZX6 |
| N-term |
C-term |
|
| Purity |
> 95% as determined by Bis-Tris PAGE |
| Endotoxin Level |
Less than 1EU per μg by the LAL method. |
| Biological Activity |
Measured by its binding ability in a functional ELISA. Immobilized IL-22, His, Human at 2μg/ml (100μl/Well) on the plate can bind Human IL22R alpha 1, hFc Tag. Test result was comparable to standard batch. |
| Expression System |
HEK293 |
| Theoretical Molecular Weight |
17.8 kDa |
| Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 28-40 kDa based on Bis-Tris PAGE result. |
| Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). |
| Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
| Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
| Target Background |
The cytokine interleukin-22 (IL-22) is a critical regulator of epithelial homeostasis. It has been implicated in multiple aspects of epithelial barrier function, including regulation of epithelial cell growth and permeability, production of mucus and antimicrobial proteins (AMPs), and complement production. |
| Synonyms |
Interleukin-22; IL-22; Cytokine Zcyto18; IL-TIF; IL-D110; TIFa; TIFIL-23; ZCYTO18 |
