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

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

Express System	HEK293
Purity	> 95% as determined by Tris-Bis PAGE
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
