Background Information: 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 murine IL-1β is a 17.5 kDa protein containing 153 amino acid residues.
Reconstitution Instructions: Reconstitute in H₂O to a concentration of 0.1-1 µg/µl. The solution can then be diluted into other aqueous buffers and stored at 4°C for 1 week or –20°C for future use.
