摘要

合成的寡脱氧核苷酸(odn)的纯化是简单地通过用可聚合的酰胺磷酸盖上失败序列,然后进行聚合。本文介绍了减少聚合单体的用量以大幅度提高ODN的萃取效率,使用离心过滤装置以简化萃取过程以及使用新鲜的酰胺磷溶液的通知。此外,还进一步证明了ODN的纯度,并讨论了ODN在自由基聚合条件下的稳定性。

A Highly Convenient Procedure for Oligodeoxynucleotide Purification
Purification of synthetic oligodeoxynucleotides (ODNs) is simply achieved by capping failure sequences with a polymerizable phosphoramidite followed by polymerization. In this article, the reduction of the amount of polymerization monomer to drastically increase ODN extraction efficiency, the use of a centrifugal filterunit to ease the extraction process and the notification of using fresh phosphoramidite solutions are described. In addition, further evidence to support the purity of ODN and discussions of ODN stability under radical polymerization conditions are provided.
