Using DNA probe specific for centromere region of chromosome 3,7,8,9 and 12, we have detected the lymphocyte of peripheral blood, the fresh tissue and the paraffin section of tumor tissue.
用3、 7、 8、 9、 1 2号染色体着丝粒特异性DNA探针，分别对外周静脉血的淋巴细胞、新鲜实体瘤组织、瘤组织石蜡切片进行染色体检测。
Moreover, digoxigenin-HBV DNA probe was highly specific , stable and of low back-ground colour.
经过试验观察还证明，此探针检测HBV DNA的特异性高，重复性好，背景显色也较低。
