Disclosed are cyanine dyes that are useful for labeling and detecting biological and other materials. The dyes are of formula (I) in which groups R3 and R4 are attached to the Z1 ring structure and groups R5 and R6 are attached to the Z2 ring structure, and n = 1, 2 or 3; Z1 and Z2 independently represent the carbon atoms necessary to complete a one ring, or two-fused ring aromatic system; at least one of groups R1, R2 , R3 , R4 , R5 , R6 and R7 is the group -E-F where E is a single bond or a spacer group and F is a target bonding group; one or more of groups R11, R12 , R13 and R14 are independently selected from the group -(CH2)k-W, where W is sulphonic acid or phosphonic acid and k is an integer from 1 to 10. The dyes may be used in fluorescence labeling applications, where the presence of one and preferably multiple water solubilising groups attached to the 3-position of the indolinium ring reduces dye-dye interactions, and hence dye-dye quenching, particularly where multiple dye molecules are attached to components such as nucleic acids, oligonucleotides, proteins and antibodies.
揭示了一种对生物和其他材料进行标记和检测有用的青菁染料。该染料具有以下结构式(I),其中基团R3和R4连接到Z1环结构,基团R5和R6连接到Z2环结构,n = 1、2或3;Z1和Z2独立表示完成一个环或两个融合环芳香系统所需的碳原子;基团R1、R2、R3、R4、R5、R6和R7中至少有一个是基团-E-F,其中E是一个单键或一个间隔基团,F是一个目标结合基团;基团R11、R12、R13和R14中的一个或多个是独立选择自羟基-(CH2)k-W的群,其中W是磺酸或膦酸,k是1到10之间的整数。这些染料可用于荧光标记应用,其中将至少一个且最好是多个水溶性基团连接到吲哚啉环的3位,可以减少染料间的相互作用,从而减少染料间的猝灭,特别是当多个染料分子连接到核酸、寡核苷酸、蛋白质和抗体等组分时。
