A fluorescent dye comprising a xanthene-derived fluorophore having the formula (I) wherein R1, R2, R3, R4, R5 and R6 are independently selected from H, alkyl, alkoxy, alcohol, ether, alkenyl, alkenoxy, aryl, aralkyl and amido, except that R1, R4 and/or R5 is not H when bonded to Y, Y1 or Y2, respectively; X is either O− or S−; and at least one of Y, Y1, Y2, Y3, Y4 and Y5 is a group for covalently bonding the dye, optionally through, the use of a coupling agent, to a target molecule, and is otherwise H. The dye may be covalently attached to a target molecule to form a complex, and the dye and/or complex finds use in cell analysis techniques, particularly pH measurement and analysis of kinetics of migration.
一种荧光染料,包括一个具有以下式子(I)的黄酮衍生荧光团:其中R1,R2,R3,R4,R5和R6独立地选自H,烷基,烷氧基,醇,醚,烯基,烯氧基,芳基,芳基烷基和酰胺,但当与Y,Y1或Y2结合时,R1,R4和/或R5不为H;X为O-或S-;并且Y、Y1、Y2、Y3、Y4和Y5中至少有一个是用于与某个靶分子共价结合染料的基团,也可以通过耦合剂进行,否则是H。该染料可以与目标分子共价结合形成复合物,并且该染料和/或复合物在细胞分析技术中有用,特别是pH测量和迁移动力学分析。
