Abstract

Analytical high-pressure anion-exchange chromatography on RPC-5 has been used to study the behaviour of a good primer, d(pT-T-A-G), and a poor primer, d(pT-T-T-T-T-T) in the E. coli polynucleotide phosphorylase-catalysed reactions of dADP, dCDP, dGDP and dTDP where the primer is extended, predominantly, by one or two nucleotides. The experiments provide some generalizations for obtaining optimal yields in preparative reactions. In the course of the experiments, examples of anomalous behaviour of oligonucleotides on RPC-5 were encountered and these are discussed.

摘要

采用RPC - 5进行分析型高压阴离子交换色谱法,研究了良好引物d(pT - T - A - G)和不良引物d(pT - T - T - T - T - T)在大肠杆菌多核苷酸磷酸化酶催化的dADP、dCDP、dGDP和dTDP反应中的行为,在这些反应中引物主要延伸一或两个核苷酸。这些实验为在制备反应中获得最佳产率提供了一些一般性结论。在实验过程中,遇到了寡核苷酸在RPC - 5上的异常行为实例,并对此进行了讨论。
