Animal-Free IL-22 Protein, Human (His)

Animal-derived-free IL-22 protein is a cytokine that regulates tissue responses during inflammation and contributes to epithelial cell regeneration to maintain barrier function and prevent tissue damage. Animal-Free IL-22 Protein, Human (His) is the recombinant human-derived animal-FreeIL-22 protein, expressed by E. coli , with C-His labeled tag. This product is for cell culture use only.

IL-22 Protein assumes a pivotal role in modulating tissue responses during inflammation, demonstrating a crucial involvement in the regeneration of epithelial cells to preserve barrier function following injury and forestall further tissue damage. Unlike most cytokines, IL-22 exerts no influence on immune cells, relying on a heterodimeric receptor comprising the specific IL22RA1 receptor, found on non-immune cells in various organs, and the shared subunit IL10RB. The binding of IL-22 to IL22RA1 activates the tyrosine kinases JAK1 and TYK2, subsequently triggering STAT3 activation. This, in turn, promotes cell survival and proliferation through the STAT3, ERK1/2, and PI3K/AKT pathways, contributing to the phosphorylation of GSK3B at 'Ser-9' and CTTN. Additionally, IL-22 fosters epithelial cell spreading.

Measure by its ability to induce proliferation in A549 cells. The ED₅₀ for this effect is <0.5 ng/mL.

Approximately 14 kDa, based on SDS-PAGE under reducing conditions.

≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 8.0, trehalose.

<0.1 EU per 1 μg of the protein by the LAL method.

It is recommended to reconstitute to a concentration of 100-200 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
