IL-22 human

Description

• General description: IL22 (interleukin 22) is a member of the IL10 related cytokine family, and this gene is localized to the human chromosome 12q15. This protein is predominantly produced by activated CD4+ T cells, and its target cells include mesangial, neuronal and hepatoma cell types.[1][2] Recombinant human IL-22 is a 33.6 kDa non-disulfide-linked homodimeric protein containing of two 147 amino acid polypeptide chains.
• Biochem/physiol Actions: IL22 (interleukin 22) is responsible for eliciting acute-phase responses including, anemia, weight loss, increase in platelet numbers, elevated serum amyloid A and fibrinogen levels and reduced levels serum albumin levels. During inflammation, this protein leads to an increase in pancreatitis-associated protein 1 (PAP1) and osteopontin in pancreatic acinar cells, which might either have protective or trophic effects.[1] This protein is involved in the crosstalk between keratinocytes and inflammatory cells. It is linked with tumorigenesis and progression of tumors. 429 C/T polymorphism in this gene is linked with susceptibility to bladder cancer.[2] In patients with recurrent pregnancy loss, the expression of IL22 is reduced in the uterine decidua, which might lead to disruption of decidual homeostasis, and hence, early loss of pregnancy.[3]

• Physical form: Lyophilized from 10 mM NaCitrate, pH 3.0
• Reconstitution: Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.5-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
