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,包括具有以下结构的黄色素衍生荧光物质(I)其中R1、R2、R3、R4、R5和R6分别独立地选自H、烷基、烷氧基、醇、醚、烯基、烯氧基、芳基、烷基芳基、芳基烷基和酰胺,但当与Y、Y1或Y2结合时,R1、R4和/或R5中的一个不是H;X为O−或S−;并且Y、Y1、Y2、Y3、Y4和Y5中至少一个是用于共价结合染料的基团,可以选择通过偶联剂将其与靶分子结合,否则为H。该染料可以与靶分子共价结合形成复合物,该染料和/或复合物可用于细胞分析技术,特别是pH测量和迁移动力学分析。
