Cy5.5 is a near-infrared (IR) fluorescence-emitting dye (excitation/emission maximum 678/694 nm). Cy7 is a near-IR fluor that is invisible to the naked eye (excitation/emission maximum 750/776 nm). It is used in in vivo imaging applications, as well as the Cy7.5 dye. See more Cyanines, also referred to as tetramethylindo(di)-carbocyanines are a synthetic dye family belonging to the polymethine group.

They were originally used, and still are, to increase the sensitivity range of See more Because they yield brighter and more stable fluorescence, cyanines can advantageously replace conventional dyes such as fluorescein and rhodamines. • Cy3 … See more Cyanines have been classified in many ways: • Streptocyanines or open chain cyanines: R2N =CH[CH=CH]n-NR2 (I) • Hemicyanines: Aryl=N =CH[CH=CH]n-NR2 (II) • Closed … See more The word cyanin is from the English word "cyan", which conventionally means a shade of blue-green (close to "aqua") and is derived from the Greek κυάνεος/κυανοῦς kyaneos/kyanous … See more WebDec 12, 2024 · FRET pairs, such as Cy3–Cy5, Cy5–Cy7, Alexa Fluor 488–555 and Alexa Fluor 555–647, have been used widely in FRET [ 22, 23, 24, 25, 26 ]. However, a high concentration of acceptors can produce background fluorescence because of crosstalk from donor excitation [ 27 ].
Web1 day ago · Within the FRET system, the energy transfer from NBDAE to Cy5 was significantly enhanced due to the introduction of MC as a central fluorophore. To better confirm whether the long-distance energy transfer from NBDAE to Cy5 could be carried out in the absence of MC, we made the hydrogel with only NBDAE and Cy5, which proved to … Web2 days ago · The CCP-FRET system has been widely used for highly sensitive DNA detection. For example, Duan et al. achieved homogeneous single nucleotide polymorphism (SNP) detection on a p53 mutation through the allele-specific extension [ 62 ]. The dGTP-FL might incorporate into the polymorphic site when the target/probe pair is complementary.
