These approaches have been employed to probe myriad biological phenomena, including protein and RNA folding [4–6], enzyme kinetics [7, 8], and even protein biosynthesis [1, 9, 10]. In particular, immobilization-based fluorescence te- niques such as total internal reflection fluorescence microscopy (TIRF-M) have recently allowed for the observation of multiple events on the millis- onds to seconds timescale [11–13]. Single-molecule fluorescence methods are challenged by the instability of single fluorophores. The organic fluorophores commonly employed in single-molecule studies of biological systems display fast photobleaching, intensity fluctuations on the millisecond timescale (blinking), or both. These phenomena limit observation time and complicate the interpretation of fl- rescence fluctuations [14, 15]. Molecular oxygen (O) modulates dye stability. Triplet O efficiently 2 2 quenches dye triplet states responsible for blinking. This results in the for- tion of singlet oxygen [16–18]. Singlet O reacts efficiently with organic dyes, 2 amino acids, and nucleobases [19, 20]. Oxidized dyes are no longer fluor- cent; oxidative damage impairs the folding and function of biomolecules. In the presence of saturating dissolved O , blinking of fluorescent dyes is sup- 2 pressed, but oxidative damage to dyes and biomolecules is rapid. Enzymatic O -scavenging systems are commonly employed to ameliorate dye instability. 2 Small molecules are often employed to suppress blinking at low O levels.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2009-06-05\u003c\/p\u003e \u003cp\u003eFormat: Hardcover\u003c\/p\u003e \u003cp\u003eISBN-13: 9789048123667\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-90-481-2368-1\u003c\/p\u003e \u003cp\u003eDimensions: 235.0cm x155.0cm\u003c\/p\u003e \u003cp\u003ePages: 179.0\u003c\/p\u003e ","brand":"Springer Netherlands","offers":[{"title":"Default Title","offer_id":45605297815692,"sku":"9789048123667","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9789048123667.jpg?v=1767711361","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9789048123667","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
