We report the successive application of classical Giemsa banding and chromosomal in situ suppression hybridization in clinical cytogenetics. The use of both techniques within one protocol requires an additional fixation of the chromosome preparations and an improved suppression of the labelled repetitive sequences. The combination of these two cytological techniques allows the high resolution mapping of translocated Y-chromosomal sequences in the chromosome set of an XX-male.
我们报告了经典吉姆萨显带和染色体原位抑制杂交技术在临床细胞遗传学中的连续应用。在同一实验方案中使用这两种技术需要对染色体标本进行额外固定,并改进对标记重复序列的抑制。这两种细胞学技术的结合使得能够在XX男性的染色体组中对易位的Y染色体序列进行高分辨率定位。
