Cyanine - Wikipedia
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. Sulfo–cyanine dyes bear one or two sulfo groups, rendering the Cy dye water-soluble, but tri- and quadri-sulfonated forms are available for even higher water solubility. [ 8 ]

Cyanine dyes - Lumiprobe
Available non-sulfonated dyes incude Cy3, Cy3.5, Cy5, Cy5.5, Cy7, and Cy7.5. Cy ® stands for 'cyanine', and the first digit identifies the number of carbon atoms between the indolenine groups. Cy2 which is an oxazole derivative rather than indolenin, is an exception from this rule.
APC-Cy7 Dye Profile - FluoroFinder
APC-Cy7 (APC-Cyanine 7) has an excitation peak at 650 nm and an emission peak at 785 nm, and is spectrally similar to APC-CF®750 (Biotium), APC-H7 (BD Biosciences), APC-eFluor™ 780 (Thermo Fisher Scientific), APC-Vio®770 (Miltenyi Biotec) and APC-Fire™ 750 (BioLegend).
CY7 (Sulfo-Cyanine7) | Fluorescent Dye - MedChemExpress
CY7 is a CY dye. CY, short for Cyanine, is a compound consisting of two nitrogen atoms connected by an odd number of methyl units. Cyanine compounds have the characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility and relatively simple synthesis.
Cy系列荧光染料 | 多荧生物 - 最全的荧光方案
所有的普通Cy染料有基本相同的斯托克位移(Stokes shift),大概15nm到20nm之间。 这个位移足够大(其实比很多荧光染料的斯托克位移都大,比如BODIPY系列),绝大部分荧光仪器都可以将荧光信号从激发光中分辨出来。 另外,溶剂和环境对普通Cy染料的荧光特性影响很小,让它们可以胜任很多条件下的显影任务,比如在低pH溶液或者脂溶性环境下都可以发出稳定的强荧光。 这类Cy染料是在普通Cy染料的发色团上加入磺酸基团从而大大增加了染料的水溶性。 磺化的 …
Cy7 (Cyanine7)荧光染料
2025年2月25日 · Cy7(Cyanine 7)是一种近红外花青素荧光染料,具有较长的发射波长,约770 nm,应用于生物成像、荧光标记和探针开发。 Cy7属于菁染料家族,其基本结构由两个吡咯啉环组成,通过一个双键连接,形成了刚性的分子框架,这使得其具有较强的荧光发射特性。
