A dye compound having the formula I:
wherein,
n is 0, 1, 2, or 3; R1 is H, alkyl, or an alkoxy group; R2 is CH2(CH2)mOH, wherein m is 0, 1, 2, or 3; X is O, S, or C(CH3)2; R is CH3, CH(CH3)2, CH2CH2OH, alkyl, alkylsulfonate, or hydroxyalkyl and B− is a counteranion.
Red- and blue-excitable dyes based on the above chemical structure are described, and reagents containing them are described for use in staining nucleic acid, more particularly for staining reticulocytes. Also described are methods for detecting reticulocytes using such compositions.
一种具有I式的染料化合物:其中,n为0、1、2或3;R1为H、烷基或烷氧基;R2为CH2(CH2)mOH,其中m为0、1、2或3;X为O、S或C(CH3)2;R为CH3、CH(CH3)2、CH2CH2OH、烷基、烷基磺酸盐或羟基烷基,B-为反离子。基于上述化学结构的红色和蓝色可激发染料已被描述,并且描述了含有它们的试剂用于染色核酸,更具体地用于染色网织红细胞。还描述了使用这种组合物检测网织红细胞的方法。
