Novel intermediates having an indolenine nucleus which are useful in the synthesis of fluorescent sulfoindocyanine dyes are described. Dyes synthesized using such intermediates do not contain a reactive group that will covalently attach to a target molecule at an amine- or hydroxy-containing site. Rather, these intermediates are linked to an enzyme substrate or a member of a specific binding pair. Also included are tyramide-comaining sulfonidocyanine dyes.
描述了具有吲哚啉核的新型中间体,这些中间体在合成荧光磺基吲哚氰染料时非常有用。使用这些中间体合成的染料不含有会在胺基或羟基含有位点与靶分子共价结合的反应性基团。相反,这些中间体与酶底物或特定结合对的成员相连。还包括含有酪胺的磺基吲哚氰染料。
