A novel method for characterizing nucleic acids. A nucleic acid is combined with a double stranded nucleic acid-specific dye to form a detectable complex between the dye and one or more double stranded structures within the nucleic acid. The combination is then exposed to varying temperatures and the fluorescence emission of the dye is measured to determine the melting temperature(s) for the double stranded structures. In some embodiments that melting temperature profile is then compared to melting temperature profiles generated for other nucleic acid(s) to discern differences between the compared nucleic acids.
一种表征核酸的新方法。将核酸与双链核酸特异性
染料结合,使
染料与核酸中的一个或多个双链结构形成可检测的复合物。然后将该复合物暴露在不同的温度下,测量
染料的荧光发射,以确定双链结构的熔化温度。在某些实施方案中,熔化温度曲线会与其他核酸的熔化温度曲线进行比较,以发现比较核酸之间的差异。
