This invention relates to derivatives of dipyrrometheneboron difluoride fluorescent dyes that have an absorption maximum at wavelengths longer than about 525 nm, and are chemically reactive with nucleic acids, proteins, carbohydrates, and other biologically derived or synthetic chemical materials. The dyes generally have the structure: ##STR1## wherein at least one of the substituents R.sub.1 -R.sub.7, is a reactive functional group, and at least one of the substituents R.sub.1 -R.sub.7 contains a bathochromic moiety. The bathochromic moiety is an unsaturated organic group, preferably heteroaryl or alkenyl. The remaining substituents, which may be the same or different, are hydrogen, halogen, alkyl (containing 1-5 carbon atoms), aryl, arylalkyl, or sulfo. The dyes are used to make novel conjugates with members of specific binding pairs that are ligands or receptors.
这项发明涉及二吡咯甲烷硼二氟化物荧光染料的衍生物,其在波长大约超过525纳米处具有最大吸收,并且在化学上与核酸、蛋白质、碳水化合物和其他生物衍生或合成化学材料发生反应。这些染料通常具有以下结构:##STR1##其中至少一个取代基R.sub.1 -R.sub.7是一个反应性官能团,至少一个取代基R.sub.1 -R.sub.7含有巴托克罗迈基团。巴托克罗迈基团是一个不饱和的有机基团,最好是杂环烷基或烯基。其余的取代基,可以相同也可以不同,是氢、卤素、烷基(含有1-5个碳原子)、芳基、芳基烷基或磺酸基。这些染料用于与特定结合对的成员制备新型共轭物,这些成员是配体或受体。
