Product Description	Recombinant Human IL-1RL1/ST2 Protein is expressed from HEK293 with His 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.

Amino Acid Range	Lys19-Phe328
Molecular Weight	The protein has a predicted MW of 36 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human IL-33, No Tag at 5ug/ml (100ul/well) on the plate. Dose response curve for Human IL-1RL1, His Tag with the EC50 of 7.4ng/ml determined by ELISA. See testing image for detail.
Product Tag	C-His
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um 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 24 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.
