The invention provides compositions electron-deficient nitrogen heterocycle-substituted fluorescein dyes and methods in which the dyes are conjugated to substrates and used as detection labels in molecular biology experiments. The electron-deficient nitrogen heterocycles include pyridine, quinoline, pyrazine, and the like. Substrates include polynucleotides, nucleosides, nucleotides, peptides, proteins, carbohydrates, and ligands.
该发明提供了一种由电子不足的氮杂环取代的荧光素染料组成的物质和方法,其中将这些染料与底物结合并用作分子生物学实验中的检测标签。电子不足的氮杂环包括吡啶、喹啉、吡嗪等。底物包括多核苷酸、核苷、核苷酸、肽、蛋白质、碳水化合物和配体。
