Lyophilized Standard Mix-Human Group 1 Panel B. PN: HG10011. One vial containing lyophilized recombinant Eotaxin, IL-1β, IL-1RA, IL-8, IL-12p70, IL-22, IP-10, MCP-1, MCP-3, and RANTES. Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits. 

STORAGE:  2-8 C in the dark.

IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

Interleukin-22 (IL-22) is a member of a group of cytokines called the IL-10 family or IL-10 superfamily (including IL-19, IL-20, IL-24, and IL-26), a class of potent mediators of cellular inflammatory responses. It shares use of IL-10R2 in cell signaling with other members of this family, IL-10, IL-26, IL-28A/B and IL-29. IL-22 is produced by activated DC and T cells and initiates innate immune responses against bacterial pathogens especially in epithelial cells such as respiratory and gut epithelial cells. IL-22 along with IL-17 is rapidly produced by splenic LTi-like cells [8] and also produced by Th17 cells and likely plays a role in the coordinated response in adaptive innate immune systems, autoimmunity and tissue regeneration. Targets of this cytokine are mostly non-hematopoietic cells such as hepatocytes, keratinocytes, and lung and intestinal epithelial cells. Pancreatic islets also express high levels of IL-22 receptor. It has been shown to induce islet beta cell regeneration.
