RecombinantIL-1β,Mouse

• Catalog Number: orb1494828
• Category: Proteins
• Description: Interleukin-1 Beta (IL-1β) is a 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 predominantly a cell-associated cytokine.Recombinant mouse Interleukin-1 Beta(rmIL-1β) produced in E. coli is a single non-glycosylated polypeptide chain containing 153 amino acids. A fully biologically active molecule, rmIL-1β is obtained by proprietary chromatographic techniques at GenScript, with an apparent molecular weight of 17.5kDa analyzed by reducing SDS-PAGE.
