A new and convenient pyrolysis mass spectrometric approach for monitoring solid phase phosphate triester synthesis of oligodeoxyribonucleotides in 5'-3' direction has been developed. The base-typical fragment ions produced by pyrolysis at 280 degrees C of the polymer-bound oligonucleotide triesters in the mass spectrometer permit the analytical monitoring of DNA chain growth, using simple mathematical operations. The base composition can be determined directly from the polymer. In addition, minor nucleosides can easily be detected.
一种新型便捷的热解质谱方法已被开发出来,用于监测5'-3'方向寡脱氧核糖核苷酸固相磷酸三酯的合成。在质谱仪中,聚合物结合的寡核苷酸三酯在280℃热解产生的碱基典型碎片离子,通过简单的数学运算即可实现对DNA链生长的分析监测。碱基组成可直接从聚合物中确定。此外,少量核苷也能轻松检测到。
