Name : Cynomolgus IL-33 Protein
Product Source :
Recombinant Cynomolgus IL-33 Protein is expressed from HEK293 with His tag at the N-Terminus. It contains His109-Ile270.[Accession | A0A2K5W3I1-1]
Molecular Weight :
The protein has a predicted MW of 19.2 kDa. Due to glycosylation, the protein migrates to 25-30 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE
Formulation :
Lyophilized from 0.22μm 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 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Cynomolgus IL-33 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SPR Data Human IL-1RL1, His Tag immobilized on CM5 Chip can bind Cynomolgus IL-33, His Tag with an affinity constant of 46.85 nM as determined in SPR assay (Biacore T200).
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.
Synonyms :
C9orf26 Z; DVS27; IL1F11; NF-HEV; NFEHEV; IL33; DV27; C9ORF26; RP11-575C20.2
