Human Interleukin-22 (IL-22), also known as T cell-derived inducible factor (ILTIF), is a cytokine that is structurally related to IL-10. Studies have shown that IL-22 induces acute-phase reactants in vitro and in vivo, suggesting that the cytokine contributes to the regulation of inflammatory responses. Recombinant human IL-22 is a 16.8 kDa protein consisting of 147 amino acids residues. MW: 16.8 kDa. Purity ≥97%
