Product Description	Recombinant Cynomolgus IL-33 Protein is expressed from HEK293 with His tag at the N-Terminus.It contains His109-Ile270.
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.
Product Category	Recombinant Protein / Antibody discovery

Protein	IL-33
Synonyms	C9orf26 Z; DVS27; IL1F11; NF-HEV; NFEHEV; IL33; DV27; C9ORF26; RP11-575C20.2
Accession	A0A2K5W3I1-1
Species	Cynomolgus
