Product Description	Recombinant Human IL-1RL1/ST2 Protein is expressed from HEK293 with hFc tag at the C-terminus.It contains Lys19-Phe328.
Product Background	IL1RL1(also known as ST2)-is a member of the IL1-receptor family-and serves as the receptor for IL-33. The-ST2 protein-has two isoforms including sST2 and the membrane-bound ST2 receptor, referred to as ST2L. Preclinical studies have demonstrated that binding of IL-33 to ST2L elicits a cardioprotective effect. ST2/IL-33 signaling may play an important role in intestinal disease.

Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 0.01 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
