本方法的特点是:在显带染色以前,用醋酸洋红染色。仅仅用盐酸处理玻片上的材料,而且在酒精处理以后,用低浓度的Leishman染色液染色而不用Giemsa或高浓度的Leishman染色液染色。 本方法的优点是:由于用醋酸洋红染色便于观察分带前染色体形态特征。不用盐酸处理根尖便于得到分离很好的染色体。本方法可以得到更多条带,而且带型十分清楚。同时带的颜色与整个染色体颜色对比适宜,便于获得清晰的照片。另外在一定程度上表明了醋酸洋红在染色体分带中的作用。 The method is characterized by: stained with acetic acid magenta before staining. The material on the slide was treated with hydrochloric acid alone and after alcohol treatment, stained with a low concentration of Leishman stain instead of Giemsa or a high concentration of Leishman stain. The advantages of this method are: As pre-banding chromatographic morphological characteristics due to acetate magenta staining. Without hydrochloric acid treatment root tip is easy to get well-separated chromosomes. This method can get more bands, and the band type is very clear. At the same time with the color of the entire chromosome color contrast, easy to get a clear picture. In addition, to a certain extent, shows the role of acetate magenta in chromosome zoning.
