Human IL-33 Protein (IL3-HE001) Summary

Product Description	Recombinant Human IL-33 Protein is expressed from E.coli without tag.It contains Ser112-Thr270.
Product Background	Interleukin-33 (IL-33) is a cytokine belonging to the IL-1 family, playing a role in inflammatory, infectious and autoimmune diseases and expressed in the cellular nucleus in several tissues. High levels of IL-33 are expressed in epithelial barrier tissues and endothelial barriers. ST2 is a receptor for IL-33, expressed selectively on a subset of Th2 cells, mediating some of their functions.
