[Abstract] DNA fragmentation with length corresponding to multiple integer of approximately 180 base pairs is a distinct feature of apoptosis in animals and programmed cell death in plants. This feature can simply be detected by DNA gel electrophoresis followed by ethidium bromide staining, although in some cases it is difficult to distinguish the DNA laddering. We herein describe a protocol to detect a programmed cell death-associated DNA laddering of plant tissues. After agarose-gel electrophoresis of genomic DNA, Southern hybridization using DIG-labeled genomic DNA probe is performed, that improves ...
[摘要] 具有对应于大约180个碱基对的多个整数的长度的DNA片段是动物中凋亡和植物中程序性细胞死亡的独特特征。 这个特征可以简单地通过DNA凝胶电泳随后溴化乙锭染色检测，尽管在一些情况下难以区分DNA梯状。 我们在本文中描述了用于检测植物组织的程序性细胞死亡相关DNA梯状的方案。 在基因组DNA的琼脂糖凝胶电泳后，进行使用DIG标记的基因组DNA探针的Southern杂交，其改善DNA梯状的检测。
