{"product_id":"roti-fluor-645-nhs-ester-1-mg-2alu","title":"ROTI Fluor 645 NHS Ester 1 mg","description":"\u003cp\u003eROTI Fluor 645 NHS Ester is a fluorescent dye NHS ester with empirical formula C₃₈H₄₃N₃K₂O₁₃S₃ and a molar mass of 924,15 g\/mol. Packed as 1 mg in plastic, it is intended for life-science use in histology, microscopy and fluorescent staining. The NHS ester group provides a reactive site for coupling the 645-class fluorophore to primary amines on biomolecules before staining or imaging. The 1 mg plastic pack is practical for small-scale labelling and for laboratories that prefer limited on-hand quantities. Manufacturer Carl ROTH states a molar mass of 924,15 g\/mol and the empirical formula C₃₈H₄₃N₃K₂O₁₃S₃, which can be used for identity checks against internal records. Fluorescent dyes in this category are applied in histological and microscopic staining to render labelled structures visible. With the NHS ester as the reactive form, ROTI Fluor 645 NHS Ester can be incorporated into amine-labelling steps that precede fluorescence observation. The 1 mg plastic presentation, formula and molar mass constitute the core specifications for this chemically defined staining reagent in life-science laboratories.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 1 mg plastic\u003c\/li\u003e\n\u003cli\u003eEmpirical formula: C₃₈H₄₃N₃K₂O₁₃S₃\u003c\/li\u003e\n\u003cli\u003eMolar mass: 924,15 g\/mol\u003c\/li\u003e\n\u003cli\u003eStorage temperature: -20 °C\u003c\/li\u003e\n\u003cli\u003eProduct class: Fluorescent dyes\u003c\/li\u003e\n\u003cli\u003eUNSPSC: 12171500\u003c\/li\u003e\n\u003cli\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.carlroth.com\/medias\/SPEZ-2ALU-EN.pdf?context=bWFzdGVyfHNwZWNpZmljYXRpb25zfDEwNDY1OXxhcHBsaWNhdGlvbi9wZGZ8YUdObEwyZzJOUzg1TWprd09UVTNNemc1T0RVMEwxTlFSVnBmTWtGTVZWOUZUaTV3WkdZfDdmNmVkMTc3NDQ5MjQxMmZkNmUxY2MwNWQ2MGE0MTIxZWJlNzJjMTlkYzA0ODAyMzJmMzYzYmU0NWNlMmQ0ZWQ\" target=\"_blank\" rel=\"noopener noreferrer\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"20\" height=\"20\" style=\"width:20px;height:20px;vertical-align:middle;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eSafety Data Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.carlroth.com\/medias\/SDB-2ALU-DE-EN.pdf?context=bWFzdGVyfHNlY3VyaXR5RGF0YXNoZWV0c3wyMzM2NzF8YXBwbGljYXRpb24vcGRmfGFHTTJMMmhsWXk4NU1qZ3pNRFUxTkRVeU1Ua3dMMU5FUWw4eVFVeFZYMFJGWDBWT0xuQmtaZ3w0YTQ0ZTYwMTAwMjMzZDQyMjIxZDU0NjA4MTU0YTI0ZThjM2QzNzAwZDEyMGVjOTExZTdlODU1NTVhZWRlNTQ5\" target=\"_blank\" rel=\"noopener noreferrer\" title=\"SDS PDF\" aria-label=\"SDS PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"20\" height=\"20\" style=\"width:20px;height:20px;vertical-align:middle;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luminix Health","offers":[{"title":"1 mg","offer_id":58621667934540,"sku":"2ALU.1","price":403.15,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/2ALU-1.jpg?v=1788085411","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/roti-fluor-645-nhs-ester-1-mg-2alu","provider":"Luminix Health","version":"1.0","type":"link"}
