Cyanine3.5-琥珀酰亞胺酯|Cy3.5 SE
我公司可為您提供各種不同活性基團(tuán)的近紅外熒光活性菁染料,如:Cyanine5 NHS ester、Cyanine3 maleimide、Cyanine7 azide、Cyanine7.5 amine等等,我們的活性基團(tuán)可以反應(yīng)連接小分子,多肽,蛋白,抗體及藥物。
水溶性CY3/Cy5/Cy7酯(Cy5, SE)是在CY3 CY5 CY7上面加上磺酸基之后增加了其水溶性,該類染料跟脂溶性染料不同的是具有良好的水溶性和親水性,這種磺酸根的CY3 CY5 CY7 末端可以鏈接NHS羥基琥珀酰亞胺酯,amine(NH2)氨基等基團(tuán)。
Cyanine菁染料是近紅外熒光染料中較常用的一類熒光染料,細(xì)胞和組織的自發(fā)熒光在近紅外波段小,能提供更高的特異性和靈敏度,菁染料是二個(gè)非區(qū)域電荷的氮原子通過(guò)聚合搭橋的方式形成的一種分子,以下圖片*詮釋:
菁染料是近紅外熒光染料中較常用的一類熒光染料,統(tǒng)的可見(jiàn)光染料相比有顯著的優(yōu)勢(shì)。由于細(xì)胞和組織的自發(fā)熒光在近紅外波段小,因此在檢測(cè)復(fù)雜生物系統(tǒng)時(shí),近紅外染料能提供更高的特異性和靈敏度。同時(shí),由于光波在近紅外區(qū)段的組織透過(guò)性更好。菁染料的摩爾吸光系數(shù)在熒光染料中是的,Cy5 hydrazide, Cy5.5 alkyne 和Cy7 NHS ester 的吸收在近紅外區(qū)背景非常低,是熒光強(qiáng)度、較穩(wěn)定的長(zhǎng)波長(zhǎng)染料。特別適合于活體小動(dòng)物體內(nèi)成像代替放射性元素。
目前市面上的菁染料價(jià)格比較高,主要是因?yàn)檩既玖? 尤其是不對(duì)稱菁染料的合成副反應(yīng)多, 副產(chǎn)物極性相近, 產(chǎn)物的分離提純相當(dāng)困難。菁染料特別是水溶性菁染料分子極性大, 分離提純?cè)郊永щy。因此像Sulfo Cy5 Carboxylic acid就比脂溶性的Cyanine7 amine這類產(chǎn)品貴一些。水溶性的Sulfo-Cyanine3 NHS ester就比脂溶性Cyanine5 azide更貴一些。
