Product name Human IL-33 protein
Sequence Amino acid sequence derived from human IL-33 isoform (O95760) (Ser112-Thr270) was expressed.
Protein length The recombinant human IL-33 consists of 160 amino acids (N-Met) and has a predicted molecular mass of 18.1 kDa. The apparent molecular mass of the human IL-33 is approximately 18 kDa in SDS-PAGE under reducing conditions due to glycosylation.
Preparation method E. coli
Purity >98 % as determined by SDS-PAGE
Alternative C9orf26; DVS27; IL1F11; NF-HEV; NFEHEV; Interleukin-33; IL33

Product Properties

Formulation Lyophilized from sterile 20 mM Tris , 50 mM NaCl, pH 5.0, 1 mM DTT, 1 mM EDTA.
Features & Benefits Endotoxin: < 0.01 EU per μg of the protein as determined by the LAL method.
Molecular weight 18 kDa
Usage notes Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized Human IL33 protein protein using the buffer we provided not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Storage instructions Lyophilized Human IL-33 proteinshould be stored desiccated below -20°C. Upon reconstitution, the protein should be stored at 4°C between 2-7 days and for future use below -20°C. For long term storage it is recommended to add a carrier protein (0.8% HSA or BSA). Please prevent freeze-thaw cycles.
Shipping The product is shipped at ambient temperature.

Additional Information

Background 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 researchers 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 plays a pivotal role in helminthic infection and allergic disorders.
