Recombinant Human IL33 Protein (Ser112-Thr270), Biotinylated
Product Description
Cat
IMP-10559
Official Symbol
IL33
Product Overview
Biotinylated recombinant human IL-33 protein (Ser112-Thr270) without tag was expressed in E. coli.
Description
The protein encoded by this gene is a cytokine that binds to the IL1RL1/ST2 receptor. The encoded protein is involved in the maturation of Th2 cells and the activation of mast cells, basophils, eosinophils and natural killer cells. Several transcript variants encoding different isoforms have been found for this gene.

Biotinylated
Molecular Mass
Predicted Molecular Mass: 18 kDa
SDS-PAGE: 18-22 kDa, under reducing conditions.
Protein length
Ser112-Thr270
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human ST2/IL-33R Fc Chimera is immobilized at 0.5 μg/mL (100 μL/well), Biotinylated Recombinant Human IL-33 binds with an ED50 of 0.900-9.00 ng/mL.
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.
Notes
Biotinylated via amines
