| Molecular Weight | The recombinant human IL1R1/Fc chimera is a disulfide-linked homodimer. The reduced monomer consists of 553 amino acids after removal of the signal peptide and has a predicted molecular mass of 63 kDa. In SDS-PAGE under reducing conditions, it migrates with an apparent molecular mass of 80-90 kDa due to glycosylation. |
| predicted N | Lys 18 |

| Purity | > 90 % as determined by SDS-PAGE |
| Protein Construction | A DNA sequence encoding the extracellular domain of human IL1R1 (NP_000868.1) (Met 1-Thr 332) was fused with human IgG1 Fc region at the C-terminus. |
| Bio-activity | 1. Measured by its binding ability in a functional ELISA. Immobilized human IL1-beta at 20 μg/ml (100 μl/well) can bind human IL1R1 Fc chimera with a linear ranger of 6.4-160 ng/ml. 2. Measured by its binding ability in a functional ELISA. 3. Immobilized human IL1B-his at 10 μg/mL (100 μl/well) can bind human IL1R1-Fc. The EC50 of human IL1R1-Fc is 0.198 μg/mL. 4. Immobilized human IL1B at 10 μg/mL (100 μl/well) can bind human IL1R1-Fc. The EC50 of human IL1R1-Fc is 0.48 μg/mL. 5. Measured by its ability to bind canine IL1B in a functional ELISA. 6. Measured by its ability to bind mouse IL1B in a functional ELISA. |

| Formulation | Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. |
| Background | Interleukin 1 receptor, type I (IL-1R1) also known as CD121a (Cluster of Differentiation 121a), is an interleukin receptor. IL-1R1/CD121a is a cytokine receptor that belongs to the interleukin 1 receptor family. This protein is a receptor for interleukin alpha (IL1A), interleukin beta (IL1B), and interleukin 1 receptor, type I (IL1R1/IL1RA). IL-1R1/CD121a is an important mediator involved in many cytokine induced immune and inflammatory responses. This protein has been characterized by pharmacological and molecular techniques in the mouse brain. The spindle-shaped astrocytes enclose the wound, separating the healthy from damaged neural tissue. The shape change and subsequent repair processes are IL-1β activity-dependent, acting through the IL-1 type 1 receptor (IL-1R1), as co-application of the IL-1type 1 receptor antagonist protein (IL-1ra) blocks IL-1β induced effects. In the spleen, a slight increase in IL-1R AcP and IL-1R1 was observed during the first hours following LPS stimulation. In conclusion, IL-1R AcP mRNA is expressed in the brain and in other tissues where IL-1R1/CD121a transcripts are found. However, the regulation of its expression is distinct from IL-1R1/CD121a. The high level of expression and the lack of regulation of IL-1R AcP transcripts in the brain under inflammatory conditions suggest that the protein might be constitutively expressed in excess. |
