Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg\/mL. Stock solutions should be apportioned into working aliquots and stored at \u0026lt;-20°C. Further dilutions should be made in appropriate buffered solutions.\u003c\/p\u003e\n\n\u003cp\u003eStorage: This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze\/thaw cycles.\u003c\/p\u003e\n\n\u003cp\u003eUsage: This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. Made in China\u003c\/p\u003e\n\n\u003cp\u003eDescription: IL-1 alpha is a non-secreted proinflammatory cytokine produced in a variety of cells including monocytes, tissue macrophages, keratinocytes and other epithelial cells. Both IL-1alpha and IL-1beta 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-1beta is a secreted cytokine, IL-1alpha is predominantly a cell-associated cytokine.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"2µg","offer_id":42882230878387,"sku":"PR1054-2","price":0.0,"currency_code":"CAD","in_stock":true},{"title":"10µg","offer_id":42882230911155,"sku":"PR1054-10","price":0.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_07ca7ef4-ea13-49bc-b713-fa015e59a73e.jpg?v=1702049725","url":"https:\/\/afsbio.com\/products\/recombinant-human-interleukin-1-alpha-rhuil-1%ce%b1-pr1054","provider":"AFSBio Inc.","version":"1.0","type":"link"}
