Webradial distance between fluorophores that the DNA helix creates, the expected FRET efficiency was ~99%. FRET testing started with the annealed Fluor./ Cy3 oligonucleotide. Unfortunately, do to Fluorescein’s degradation, we were unable to obtain any FRET data. We then switched to the Cy3/ Cy5 pair and measured a FRET efficiency of 60%. WebAlexa Fluor 680 dye. Invitrogen Alexa Fluor 680 dye is a bright, near-IR fluorescent dye with excitation ideally suited for the 633 nm laser line. For stable signal generation in imaging …

WebAug 1, 2004 · Competition between FRET from Cy3 to Cy5 and FRET from Cy3 to Cy5.5 partly explains the difference, but there definitely exist effects of two-step FRET from Cy3 to Cy5 to Cy5.5; Cy5.5 intensity in its low FRET state is higher when Cy5 is active than after Cy5 bleaching (Fig. 6 a). The extent of FRET between Cy5 and Cy5.5 will be quantified …
WebThe proximity of the Cy3 and Cy5 cores in the parent structure facilitated FRET and enabled the probe to emit a strong fluorescence emission at 660 nm upon excitation at 530 nm. Upon addition of ONOO −, the Cy5 moiety was selectively oxidised to its oxindole derivative, quenching the FRET process. This chemical transformation is shown in ... craigslist used boats north dakotacraigslist used boats ohioWebCy3 and Cy5 were co-localized by the software and time traces of fluorescence intensities for both fluorophores were plotted (Fig. 3B).
