Chemically reactive carbocyanine dyes incorporating an indolium ring moiety that is substituted at the 3-position by a reactive group or by a conjugated substance, and their uses, are described. Conjugation through this position results in spectral properties that are uniformly superior to those of conjugates of spectrally similar dyes wherein attachment is at a different position. The invention includes derivative compounds having one or more benzo nitrogens.
本发明描述了
化学反应性的碳
氰染料,其中包含一个在3位被反应基团或共轭物质取代的
吲哚环基团,并且它们的用途。通过这个位置的共轭作用,使得光谱性质比在不同位置连接的光谱相似
染料的共轭物质均匀优越。本发明包括具有一个或多个苯并氮原子的衍生化合物。
