IL-22 Protein, Human (HEK293)

IL-22 Protein, Human (HEK293) is a HEK293 cell derived cytokine protein and intricate member of the immune response.

Interleukin-22 (IL-10-related T cell-derived inducible factor/IL-TIF/IL-22) is a novel cytokine belonging to the IL-10 family. Recombinant humanIL-22 (hIL-22) is found to activate the signal transducers and activators of transcription factors 1 and 3 as well as acute phase reactants in several hepatoma cell lines, suggesting its involvement in the inflammatory response. IL-22 is a member of interleukin-10 family of cytokines, which also includes IL-19, IL-20, and IL-24 in addition to IL-10 and a number of its viral homologs^[1].

Measured by its ability to induce IL-10 secretion in COLO 205 (human colon carcinoma cells). The ED₅₀ for this effect is less than 0.3 ng/mL.

16-30 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized after extensive dialysis against PBS.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 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. 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.
