    Abstract: Protein dyes whose molecular structure is that of a coumarin moiety coupled to a quaternary ammonium heterocycle through a vinyl or polyvinyl linkage demonstrate the ability to associate with proteins in a non-covalent, non-specific manner at low pH, where the associated form displays a significantly higher fluorescence emission than the unassociated form. This makes the dyes useful as selective labels for proteins at the low pH and eliminates the need for the removal of extraneous components from the medium in which the proteins reside prior to detection.

    Abstract translation: 其分子结构是通过乙烯基或聚乙烯基键连接到季铵杂环的香豆素部分的蛋白质染料证明了在低pH下以非共价,非特异性方式与蛋白质缔合的能力,其中相关联的形式显示 荧光发射明显高于非相关形式。 这使得染料可用作蛋白质在低pH下的选择性标记,并且不需要从检测前蛋白质存在的培养基中去除外来成分。
