实验中用碱基分析方法观察了硫芥烃化DNA在37℃、0.03M磷酸缓冲液(pH7.2)中的自发性去嘌呤反应。烃化DNA分子内的鸟嘌呤和腺嘌呤随着时间的进程都明显减少。它们脱落的半值期分别为4及24
In the experiment, the spontaneous purine reaction of sulfuryl mustard alkalized DNA in 0.03 M phosphate buffer (pH 7.2) was observed by the base analysis method. Both guanine and adenine in the alkylated DNA molecules decreased significantly over time. The half-value periods for their shedding are 4 and 24, respectively
