| Purity | > 98 % as determined by SDS-PAGE |
| Protein Construction | A DNA sequence encoding the human IL1RL1 isoform A (NP_057316.3) (Met 1-Ser 328) was expressed, fused with a polyhistidine tag at the C-terminus. |
| Bio-activity | 1. Measured by its binding ability in a functional ELISA. 2. Immobilized recombinant human IL33 (P 10368-HNAE) at 10 μg/mL (100 μl/well) can bind biotinylated human IL1RL1 (isoform A) (P 13034-H08H) with a linear range of 0.032-8 μg/ml. |

| Formulation | Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. |
| 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. |
