Interleukin 33 (IL33), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as protein structure analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

This recombinant protein was expressed from a DNA sequence encoding the C-terminal segment of human IL33 (NP_002296.1) (Ser 112-Thr 270).

Activity: Measured by its binding ability in a functional ELISA . Immobilized human IL33 at 10 µg/ml (100 µg/well) can bind human IL1RL1 with a linear range of 0.31-5 ng/ml .

Formulation: Lyophilized in 140 mM NaCl, 2.7 mM KCl, 10 mM Na₂HPO₄, 1.8 mM KH₂PO₄, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween-80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 25 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.
