Gene

The Interleukin-1 family (IL-1 family) is a group of 11 cytokines, which plays a central role in the regulation of immune and inflammatory responses to infections or sterile insults. Rec. E. coli interleukin-1 for cell culture or antibody production.

 

Keep at

The lyophilized IL-1 alpha recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted IL-1 alpha is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing IL-1 alpha recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

About recombinant protein

IL-1β is a non-secreted proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. Both IL-1α and IL-1β 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-1β is a secreted cytokine, IL-1α is predominantly a cell-associated cytokine. Recombinant rat IL-1α is a 17.7 kDa protein containing 155 amino acid residues.
