摘要 从检测的原理、局限性和影响因素等方面对几种主要的DNA单链断裂的检测技术包括快速沉降技术、碱性解旋、碱性洗脱和单细胞凝胶电泳进行了综述.重点介绍了单细胞凝胶电泳的产生和发展、检测范围和影响因素,为检测DNA损伤程度提供了依据. Several kinds of techniques of detecting DNA single strand breakage in cells are discussed, namely, velocity sedimentation, alkali unwinding, alkali elution, and single cell gel electrophoresis, with regard to their principle, limitations, and influence factors. More emphasis is laid on the history, development, detecting range and different factors. Supporting bases are alamo provided for detecting the degree of DNA damage.
