Abstract
Triple staining with fluorochromes (DA/DAPI/CMA) and C-banding were used to characterize the composition of Pseudonannolene strinatii heterochromatin. C-banding showed C+ bands of different labeling intensity on chromosomes 1 and 2 in some cells. Fluorochrome staining revealed DAPI+ regions corresponding to the C-banding pattern, indicating that the heterochromatin of this species is abundant in AT-rich sequences.
摘要
使用荧光染料（DA/DAPI/CMA）三重染色和C带技术来表征斯特里纳蒂假南娜瘦姬蜂异染色质的组成。C带显示在一些细胞中，1号和2号染色体上有不同标记强度的C+带。荧光染料染色揭示了与C带模式相对应的DAPI+区域，表明该物种的异染色质富含富含AT的序列。
