z-series image of mouse ES cells with a multi-copy alpha-globin BAC insertion. H3K9me3 (blue) marks the heterochromatic core which largely colocalizes with combined FISH signal from the lac operator repeats and BAC vector backbone (green). In contrast the BAC FISH signal (red) is more peripheral.

小鼠胚胎干细胞z系列图像，其中包含多拷贝α-珠蛋白BAC插入。H3K9me3（蓝色）标记了异染色质核心，该核心与来自乳糖操纵子重复序列和BAC载体骨架的联合FISH信号（绿色）在很大程度上呈共定位。相比之下，BAC FISH信号（红色）则更为周边。
