Not stable in aqueous solutions (half-life value of 1 h at pH 7.5\/RT).For stock solutions of 200-250 mM heat shortly (approx. 30 mins) to 30 °C.Stock solutions should be stored at -20 °C. Short term storage of few weeks may be done at +4 °C in the dark.PMSF reacts with thiols. DTT and β-mercaptoethanol reduce the inhibitory effect.At every stage of isolating or purifying the proteins, PMSF should be added fresh from the stock solution. PMSF is often not sufficient as the only protease inhibitor in the preparation to protect against decomposition processes, as for example high salt concentration (3.0 M) impairs the inhibitory effect of PMSF.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\n\u003c!-- DeliveryText --\u003e\n\n\u003c!-- printCatalogLink --\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv style=\"margin-top:1.5rem;\"\u003e\n  \u003ca href=\"https:\/\/www.carlroth.com\/medias\/Info-Brochure-ProteaseInhibitors-EN.pdf?context=bWFzdGVyfHRlY2huaWNhbERvY3VtZW50c3wyMzk1MzJ8YXBwbGljYXRpb24vcGRmfGRHVmphRzVwWTJGc1JHOWpkVzFsYm5SekwyZzNPUzlvTlRNdk9URXhOalkwTWpJeE16a3hPQzV3WkdZfDJlNmI4ZGFlNzRjOWZlMGNjMDY2YzZlN2QxNDdjNGE5NmI1OTg5Y2Y0ZjZkZjIyMTI2MzRmN2E2NGE2ODhiZGY\" target=\"_blank\" rel=\"noopener noreferrer\" download style=\"display:inline-flex; align-items:center; gap:.65rem; text-decoration:none; color:#000; font-weight:600; font-size:1rem;\"\u003e\n    \u003csvg style=\"width:1.65rem;height:1.65rem;color:#dc2626;flex-shrink:0;\" viewbox=\"0 0 384 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" aria-hidden=\"true\"\u003e\n      \u003cpath d=\"M64 0C28.7 0 0 28.7 0 64V448c0 35.3 28.7 64 64 64H320c35.3 0 64-28.7 64-64V160H256c-17.7 0-32-14.3-32-32V0H64z\" fill=\"#ffffff\" stroke=\"currentColor\" stroke-width=\"32\"\u003e\u003c\/path\u003e\n      \u003cpath d=\"M256 0V128H384L256 0z\" fill=\"currentColor\"\u003e\u003c\/path\u003e\n      \u003ctext x=\"192\" y=\"380\" font-family=\"Arial, Helvetica, sans-serif\" font-size=\"110\" font-weight=\"bold\" fill=\"currentColor\" text-anchor=\"middle\"\u003ePDF\u003c\/text\u003e\n    \u003c\/svg\u003e\n    Technical Documentation (PDF)\n  \u003c\/a\u003e\n\u003c\/div\u003e","brand":"Carl Roth","offers":[{"title":"348 mg \/ 1 piece","offer_id":56169096446284,"sku":"6367.4","price":19.9,"currency_code":"EUR","in_stock":true},{"title":"348 mg \/ 6+ pieces","offer_id":56169096479052,"sku":"6367.4","price":18.91,"currency_code":"EUR","in_stock":true},{"title":"348 mg \/ 24+ pieces","offer_id":56169096511820,"sku":"6367.4","price":17.91,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 1 piece","offer_id":56169096544588,"sku":"6367.1","price":42.9,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 6+ pieces","offer_id":56169096577356,"sku":"6367.1","price":40.76,"currency_code":"EUR","in_stock":true},{"title":"5 g \/ 24+ pieces","offer_id":56169096610124,"sku":"6367.1","price":38.61,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 1 piece","offer_id":56169096642892,"sku":"6367.2","price":138.7,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 6+ pieces","offer_id":56169096675660,"sku":"6367.2","price":131.77,"currency_code":"EUR","in_stock":true},{"title":"25 g \/ 24+ pieces","offer_id":56169096708428,"sku":"6367.2","price":124.83,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 1 piece","offer_id":56169096741196,"sku":"6367.3","price":418.2,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 6+ pieces","offer_id":56169096773964,"sku":"6367.3","price":397.29,"currency_code":"EUR","in_stock":true},{"title":"100 g \/ 24+ pieces","offer_id":56169096806732,"sku":"6367.3","price":376.38,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/6367-SF-1000Wx1000H_a4dce365-f6b6-4443-ba48-a86243fd110f.jpg?v=1766442323","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/phenylmethyl-sulphonyl-fluoride-6367","provider":"Luminix Health","version":"1.0","type":"link"}
