Description of Rat IL-1 alpha
Recombinant Rat Interleukin-1 alpha (IL-1 alpha) is a 17.7 kDa protein consisting of 155 amino acid residues. Rat IL-1 alpha 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 ≤ 0.005 ng/ml was determined by the dose-dependent stimulation of the proliferation of murine D10S cells. It corresponds to a specific activity of ≥ 2.0 x 108 units/mg.
Reconstitution
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.
Stability
The lyophilized protein is stable at room temperature for 3 weeks, but best stored desiccated below -18°C. Upon reconstitution IL1A should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA, order number: 2835.955.xyz or 2835.958.xyz, or BSA, order number: 2835.919.xyz). Please avoid repeated freeze-thaw cycles.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Pro-His-Ser-Phe.
