A method is described for the separation of 13 major and minor ribo- and deoxyribonucleosides in a single chromatographic run using high-performance liquid chromatography on strongly acidic cation-exchange columns. The method proved useful for the routine determination of small amounts of ribonucleic acid impurities in deoxyribonucleic acid preparations and vice versa. About 3% or even less of nucleic acid contamination in a given sample can be easily detected and quantitatively determined under the conditions used.
本文描述了一种使用高效液相色谱法在强酸性阳离子交换柱上单次色谱运行中分离13种主要和次要的核糖核苷及脱氧核糖核苷的方法。该方法被证明可用于常规测定脱氧核糖核酸制剂中少量的核糖核酸杂质,反之亦然。在所用条件下,可以轻松检测并定量测定给定样品中约3%甚至更少的核酸污染。
