Description
IL1AMouse Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 165 amino acids (115-270a.a.) and having a molecular mass of 19.0kDa (Molecular size on SDS-PAGE will appear at approximately 18-28kDa). IL1A is expressed with a 9 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
Product Specs
Interleukin 1 alpha (IL-1 alpha), also known as hematopoietin 1, is a cytokine belonging to the interleukin 1 family. Encoded by the IL1A gene in humans, IL-1 alpha plays a crucial role in inflammation, fever, and sepsis. Inhibitors of IL-1 alpha are being developed to modulate these processes for therapeutic purposes. Primarily produced by neutrophils and macrophages, as well as endothelial and epithelial cells, IL-1 alpha binds to the IL-1 receptor, playing a vital role in regulating immune responses. It is also involved in activating tumor necrosis factor-alpha (TNF-alpha) and exhibits physiological, metabolic, and hematopoietic activities.
Recombinant Mouse IL1A, produced in Sf9 Baculovirus cells, is a single, glycosylated polypeptide chain comprising 165 amino acids (115-270a.a.). With a molecular weight of 19.0 kDa (appears as approximately 18-28 kDa on SDS-PAGE), this IL1A is expressed with a 9 amino acid His tag at the C-terminus and purified using proprietary chromatographic techniques.
The IL1A protein solution, provided at a concentration of 0.5 mg/ml, is prepared in Phosphate Buffered Saline (pH 7.4) with 10% glycerol.
For short-term storage (up to 2-4 weeks), store the entire vial at 4°C. For extended storage, freeze the product at -20°C. It is recommended to add a carrier protein (0.1% HSA or BSA) for long-term storage. Avoid repeated freeze-thaw cycles to maintain protein integrity.
The purity of this product is greater than 90%, as determined by SDS-PAGE analysis.
The ED50, determined using a cell proliferation assay with D10.G4.1 mouse helper T cells, is less than 0.15 ng/ml.

Product Science Overview
IL-1α exerts its effects by binding to specific cell surface receptors, namely IL-1RI and IL-1RII, which are shared with IL-1β. This cytokine is involved in the activation of various signaling pathways that lead to the production of other proinflammatory cytokines and the initiation of acute-phase responses .
IL-1α is a pleiotropic cytokine, meaning it has multiple effects on different cell types. It plays a significant role in:
- Innate Host Defense: Triggering the production of other proinflammatory cytokines in target cells.
- Inflammatory Responses: Initiating and sustaining inflammation.
- Apoptosis: Inducing programmed cell death in response to cell injury .
Recombinant IL-1α is widely used in research to study its role in immune responses and inflammation. It is also utilized in various bioassays to understand its biological activity and interactions with other cytokines and receptors .
The recombinant IL-1α protein is typically lyophilized (freeze-dried) for stability and should be stored desiccated below -18°C. Upon reconstitution, it should be stored at 4°C for short-term use and below -18°C for long-term storage. It is recommended to add a carrier protein, such as 0.1% HSA or BSA, to prevent freeze-thaw cycles .
