Asymmetric cyanine fluorescent dyes are represented by general formula I. These kinds of dyes may be used as a staining agent for nucleic acids, with the spectra at 600-900 nm in the near-infrared region and without interference from background fluorescence. These kinds of dyes may be useful with small-type red semiconductor lasers as the light source (such as 633 nm). Compositions comprising these dyes and methods for staining biological samples using these dyes or compositions are also provided.
非对称青光菁荧光染料由一般式I表示。这种染料可用作核酸染料,其光谱位于近红外区间的600-900 nm,并且不受背景荧光的干扰。这种染料可与小型红色半导体激光器一起使用作为光源(例如633 nm)。还提供了包含这些染料的组合物以及使用这些染料或组合物染色生物样本的方法。
