摘要

我们开发了一种简单快速的方法(“灯芯印迹”),用于检测植物中特定DNA序列i的存在,使用放射性标记DNA探针。这种方法只需要少量的组织,大约15-25毫克。每天可以轻松提取和染色100多个样品。它适用于各种物种和组织,包括叶子、胚胎和愈伤组织。该方法非常适合筛选大量假定的转化体,特别是未通过先前选择筛选的群体。

A rapid screen for the detection of specific DNA sequences in plants

We have developed a simple and quick method (“wick blot”) for detecting the presence of specific DNA sequences i in plants, using radiolabeled DNA probes. The method requires only small amounts of tissue, about 15–25 mg. More than a hundred samples per day can be easily extracted and blotted. It works well on various species and tissues, including leaves, embryos, and callus. The method is ideally suited for screening large numbers of putative transformants, especially populations that have not been screened by prior selection.
