产品简介：

磺化Cy7.5(sulfo Cyanine 7.5; sulfo Cy7.5)是一种发近红外(NIR)荧光的花青素类荧光染料。磺化Cy7.5是磺化修饰过的Cy7.5，水溶性好。磺化Cy7.5的消光系数高，荧光也很亮，并且对pH不敏感，并且由于它的荧光波长（Em：797nm）恰好处于肌体组织近红外窗口 I 的区域（肌体的血液，体液和组织此区域背景荧光弱，而长波长穿透性强），所以磺化Cy7.5常应用于小动物活体体内成像中。磺化Cy7.5可以用来标记蛋白，抗体，多肽，核酸分子，纳米粒等。由于强水溶性加带电荷，磺化花青素标记的生物分子更稳定，不易产生疏水性聚集。

本产品磺化Cy7.5荧光基(fluorophore)是优化后的结构，多次甲基(polymethine)桥链经环己烯固化，荧光***产率提高了20%，从而使荧光更亮。

磺化Cy7.5-马来酰亚胺的水溶性非常好，所以可以在水相的标记反应体系中直接使用，不需要有机溶剂助溶，特别适合标记对有机溶剂敏感的生物分子。另外磺化Cy7.5水溶性很好，并且染料分子本身带电荷，标记后不会引发目标分子疏水性聚集，提高荧光标记产物的稳定性。磺化Cy7.5-伯胺也溶于甲醇，DMSO，DMF等有机溶剂，标记反应也可以在纯有机溶剂中进行。如需脂溶性Cy7.5染料，可选择普通花青(cyanine)，即Cy7.5-马来酰亚胺( D10039 )。

磺化Cy7.5-马来酰亚胺标记后的产物Ex/Em是788/808nm。和它具有相似荧光特性的染料包括Alexa Fluor 790，DyLight 800，ICG等。
