Description générale

IL-1α 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 human IL-1α is an 18.0 kDa protein containing 159 amino acid residues.
Product Source: Protein is expressed in E.coli.
The protein is manufactured without the use of any animal products/reagents and is considered Animal-Free and can be used in protocols where possible transmisson of animal viruses and contamination must be avoided.
