Lead Time
Basically, we can dispatch the products out in 5-10 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Description
IL-22 signals through the IL-22R1/IL-10R2 heterodimer to activate JAK/STAT3 pathways critical for epithelial barrier defense and tissue repair, making a well-characterized recombinant form essential for dissecting these mechanisms. This tag-free human IL-22 (aa 34–179) encompasses the mature secreted sequence and demonstrates confirmed receptor engagement, with an ED50 of 34.43 ng/ml for binding recombinant human IL-22RA2 in functional ELISA—supporting its use as a coating antigen for antibody screening, a positive control in cytokine detection assays, and a ligand in JAK/STAT signaling studies. The endotoxin level below 1.0 EU/μg satisfies the stringent criteria needed to prevent LPS-driven artifacts in cell-based activation or differentiation assays and in vivo inflammation models. Purity exceeding 95% by SDS-PAGE, combined with this low endotoxin burden, provides a suitable basis for generating reliable dose-response data in STAT3 phosphorylation readouts and antibody validation workflows.
