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。
马来酰亚胺(maleimide)是生物标记反应中常用的基团,它可以和巯基(-SH)通过亲和加成反应生成稳定的巯醚(thioester)结构从而实现标记。尽管胺基(比如赖氨酸精氨酸侧链)也有亲和性,但在中性或微酸性缓冲液中,马来酰亚胺选择性标记巯基(反应速度比胺基快>1000倍)。标记反应反应迅速,选择性高,产率好,另外,巯基是一种在生物分子中***存在的官能团,比如蛋白中的丝氨酸(cysteine)和双硫键等,因此马来酰亚胺/巯基(maleimide/thiol)标记已成为仅次于NHS/胺基标记的***常用生物连接反应(bioconjugation)。
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,吲哚菁绿(indocyanine green, ICG)等。
