Description of Murine IL-1 alpha

Recombinant murine Interleukin-1alpha (IL-1alpha), produced in E.coli is a 17.9 kDa protein with 156 amino acid residues. It is a non-secreted proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. Both IL-1 alpha and IL-1 beta binds to the same receptor and has similar if not identical biological properties. These cytokines have a broad range of activities including, stimulation of thymocyte proliferation, by inducing IL-2 release, B-cell maturation and proliferation, mitogenic FGF-like activity and the ability to stimulate the release of prostaglandin and collagenase from synovial cells. However, whereas IL-1 beta is a secreted cytokine, IL-1 alpha is a predominantly a cell-associated cytokine.


Biological Activity

The ED50 of ≤ 0.002 ng/ml was determined by the dose-dependent stimulation of the proliferation of murine D10S cells. It corresponds to a specific activity of ≥ 5.0 x 108 units/mg.



We recommend a quick spin followed by reconstitution in water to a concentration of 0.1-1.0mg/ml. This solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or 20°C for future use.



The lyophilized protein is stable at room temperature for a few weeks, but best stored at 20°C. Reconstituted murine IL-1 alpha should be stored in working aliquots at 20°C. For Long term storage we recommend the addition of a carrier Protein e.g. 0,1% highly pure HSA (order number: or BSA (order number: Please avoid repeated freeze-thaw cycles.
