Background: IL-1 receptor– like 1 (IL1RL1) is a membrane receptor involved in TH2 inflammatory responses and eosinophilia. It has previously been described that levels of the interlukin-1 like 1 (IL1RL1) protein can be used to diagnose cardiovascular disease and determine the prognosis for a patient with cardiovascular disease. The ligand for IL1RL1 has been described, and named IL-33. Mutants in IL1RL1 have been associated with blood eosinophil counts in a genome-wide association study and with asthma in family-based and case-control studies. As an important mediator involved in many immune and inflammatory responses, this cytokine has been implicated as a regulator of both the development and effector phases of type 2 helper T cell responses, and as a negative feedback modulator of macrophage pro-inflammatory function. IL33 is a specific ligand of ST2L and induces production of Th2 cytokines.
Activity: Immobilized human IL-33 at 10 μg/ml (100 μl/well) can bind human IL1RL1 / Fc Chimera with a linear range of 0.31-5 ng/ml.
Sequence: Met 1-Phe 328
Purity: > 95 % as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile PBS, pH 7.4
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: Please refer to the printed manual for detailed information.
Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
Calculated MW: 67.1 kDa
Observed MW: 85-95 kDa
Storage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.
Shipping: This product is provided as lyophilized powder which is shipped with ice packs.
