摘要
目前国内普遍采用的往返电泳法是检测马铃薯类病毒的主要方法之一,但该方法存在灵敏度低,重复性差等问题。因此,针对上述问题总结出一些技术要点:(1)保证植物生长环境及正确取样;(2)提高凝胶中RNA的浓度和质量;(3)控制好反向电泳的温度和时间;(4)及时更换染色液。
At present, return-polyacrylamide gel electrophoresis (R-PAGE) is a commonly used method for potato spindle tuber viroid (PSTVd) detection in China. But, there are some drawbacks in this technique, such as low sensitivity and poor repeatability. In response to the problems mentioned above, some technical points were pointed out based on the author's experience for PSTVd detection:(1) optimization of plant growth environments and proper sampling;(2) increasing the concentration and quality of RNA in the gel;(3) the control of temperature and time in reverse electrophoresis;and (4) replacing the staining solution timely.
