小鼠白介素-33|Murine IL-33

Synonyms :

NF-HEV

Description :

IL-33 is a proinflammatory protein that shares structural and functional characteristics with the IL-1 cytokine family. It binds and signals through the IL-1RL1/ST2 receptor activating NF-kappaB and MAP kinases. IL-33 induces production of TH2 cell related cytokines, including IL-4, IL-5 and IL-13, and exerts multiple inflammation related bioactivities. Recombinant murine IL-33 is a 17.5 kDa protein containing 158 amino acid residues.

Source :

E.coli

Stability :

The lyophilized protein is stable for at least 2 years from date of receipt at -20⁰C. Reconstituted IL-33 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20⁰C. Avoid repeated freeze/thaw cycles.

Purity :

Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin Level :

Endotoxin level is less than 0.1 ng per μg (1EU/μg).

Biological Activity :

The ED₅₀ was determined by the dose-dependent stimulation of the proliferation of murine D10S cells is ≤ 0.5 ng/ml, corresponding to a specific activity of ≥ 2 x 10⁶units/mg.
