名称：原装正品| Recombinant Murine IL-1β
Source: E.coli. IL-1β is a proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells.
Purity: Greater than 98% by SDS-PAGE gel and HPLC analyses. Both IL-1α and IL-1β binds to the same receptor and has similar if not identical biological properties.
Description: 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. The ED50 as determined by the dose-dependent stimulation of murine D10S cells is ≤ 0.002 ng/ml, corresponding to a specific activity of ≥ 5 x 108 units/mg.
