Abstract

A new RNA-selective fluorescent dye integrated with a thiazole orange and a p-(methylthio)styryl moiety shows better nucleolus RNA staining and imaging performance in live cells than the commercial stains. It also exhibits excellent photostability, cell tolerance, and counterstain compatibility with 4',6-diamidino-2-phenylindole for specific RNA-DNA colocalization in bioassays.

摘要

一种新的整合了噻唑橙和对(甲硫基)苯乙烯基部分的RNA选择性荧光染料,在活细胞中显示出比商业染料更好的核仁RNA染色和成像性能。它还具有出色的光稳定性、细胞耐受性,并且在生物测定中与4',6-二脒基-2-苯基吲哚用于特定RNA-DNA共定位时具有复染兼容性。
