产品名称:
IL-1 beta Recombinant Protein
别名:
IL-1, IL1F2, IL1-BETA, Interleukin-1 beta, Catabolin, IL-1 beta
表达系统:
E. coli
保存温度:
The lyophilized IL-1 beta recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted IL-1 beta 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 beta 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.

功能与背景:
IL-1β is a 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-1β is a 17.3 kDa protein containing 153 amino acid residues.
