Recombinant Human IL33 protein

Cat.No.: IL33-215H
Product Overview: Recombinant Human IL33(Ser 112-Thr 270) fused with an initial Met at the N-terminus was expressed in E. coli.
Description: Interleukin 33 (IL-33), also known as DVS27 or NF-HEV (Nuclear Factor from High Endothelial enules), is a proinflammatory protein and a chromatin-associated cytokine of the IL-1 family with high sequence and structural similarity to IL-1 and IL-18. IL-33 protein is expressed highly and rather selectively by high endothelial venule endothelial cells (HEVECs) in human tonsils, Peyers's patches, and lymph nodes. IL-33 protein has transcriptional regulatory properties, and the researches suggested that IL-33 is a dual-function protein that might act both as a cytokine and as an intracellular nuclear factor. As a type 2 cytokines, IL-33 protein also play a pivotal role in helminthic infection and allergic disorders.
Source: E. coli
Species: Human
Predicted N Terminal: Met
Form: Lyophilized from sterile PBS, pH 7.4.
Bio-activity: 1. Measured by its binding ability in a functional ELISA. Immobilized human IL-33 at 10 μg/ml (100 μl/well) can bind human IL1RL1 with a linear range of 0.31-5 ng/ml.
2. Measured in a cell proliferation assay using D10.G4.1 mouse helper T cells costimulated with anti-CD3. The ED50 for this effect is typically 0.15-0.6 ng/mL.
Molecular Mass: The recombinant human IL33 comprises 160 amino acids and predicts a molecular mass of 18 kDa as estimated in SDS-PAGE under reducing conditions.
Purity: > 98 % as determined by SDS-PAGE
Stability: Samples are stable for up to twelve months from date of receipt at -70 centigrade
Storage: Store it under sterile conditions at -20centigrade to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
