Thiol-reactive, near infrared dye Cyanine7.5 for the labeling of protein SH groups, an analog of Cy7.5® maleimide.

Most proteins contain sulfhydryl groups which can be selectively labeled with maleimides. With this reagent, these proteins can be converted to near infrared (NIR) fluorescent conjugates. After it, the conjugates can be used in non-invasive live organism imaging to study distribution of the protein in tissues and organs.

硫醇反应性近红外染料 Cy7.5 用于标记蛋白质 SH 基团,Cy7.5® 马来酰亚胺的类似物。

大多数蛋白质含有巯基,可以选择性地用马来酰亚胺标记。 使用该试剂,这些蛋白质可以转化为近红外 (NIR) 荧光结合物。 之后,缀合物可用于非侵入性活体生物成像,以研究蛋白质在组织和器官中的分布。
