水溶性的近紅外染料sulfo-cyanine7，胺活性琥珀酰亞胺酯。

一種改進的sulfo-cyanine7 Cy7熒光產率提高20%，模擬，和更高的光穩(wěn)定性。這種熒光染料特別適用于近紅外成像。

近紅外熒光成像利用特定波長范圍內生物組織的透明度。該方法是非破壞性的，并且允許監(jiān)測活體中各種標記分子的分布。

sulfo-cyanine7 NHS酯試劑可以準備sulfo-cyanine7-labeled生物分子，如蛋白質，輕松。染料標記分子可用于各種研究和***設計相關實驗。

該試劑具有很高的水溶性，特別適用于精細蛋白質和易變性的蛋白質的標記。非磺化cyanine7 NHS酯溶于有機相。

CY花菁染料的優(yōu)點：

1：菁染料的摩爾吸光系數(shù)在熒光染料中是的

2：細胞和組織的自發(fā)熒光在近紅外波段zui小

3：更高的特異性和靈敏度

4：光波在近紅外區(qū)段的組織透過性更好

5：染料細胞毒性小 可用于標記抗體 蛋白 細胞。

因此CY花菁染料是非常適合做小鼠活體成像的熒光染料

 
CY花菁染料的價格：

目前市面上的菁染料價格比較高，主要是因為菁染料, 尤其是不對稱菁染料的合成副反應多, 副產物極性相近, 產物的分離提純相當困難。菁染料特別是水溶性菁染料分子極性大, 分離提純越加困難，因此帶磺酸根的水溶花菁染料比脂溶的貴一些。我公司公司提供的CY染料 各種活性基團的脂溶的2050/10MG  水溶的各種基團的2850/10MG。
