我们已经建立了一种方法,使用一种传统的细胞分选机,配备一台单一的氩激光来分选完整的人类染色体,这种染色体可以用作生产巨大DNA片段的来源。为了提高分选分辨率,避免染色体DNA的破坏,对分选设备和分选方法进行了多方面的改进。用这种改进的方法从B淋巴母细胞系GM00130B中分选出21号和22号染色体,用稀有限制性内切酶Noti酶切后,以Alu重复序列为探针,进行脉冲场凝胶电泳和Southern杂交分析。从50kb到2.5Mb以上的25个分离的Noti巨型DNA片段被分离出来,并且每个染色体的大小分布模式是唯一的,这表明完整的染色体成功地进行了分选。这些Alu阳性的Noti DNA片段在第21和22号染色体上的累积大小分别为22.7Mb和25.5Mb。这些值是第21号染色体(48Mb)和22号染色体(52Mb)估计大小的47%和49%。
We have established a method using a conventional cell sorter equipped with a single argon laser to sort intact human chromosomes that can be used as a source for the production of giant DNA fragments. Various improvements were made to both the equipment and sorting method to enhance the sorting resolution and avoid destruction of chromosomal DNA. Using this improved method chromosomes 21 and 22 were sorted from the B-lymphoblastoid line GM00130B, digested with the rare cutting restriction endonuclease NotI, and analyzed by pulsed field gel electrophoresis followed by Southern hybridization using the Alu repetitive sequence as a probe. More than 25 discrete NotI giant DNA fragments ranging from 50 kb to longer than 2.5 Mb were separated and the size distribution pattern was unique for each chromosome, indicating successful sorting of intact chromosomes. The cumulative size of these Alu-positive NotI DNA fragments were 22.7 Mb and 25.5 Mb for chromosomes 21 and 22, respectively. These values are 47% and 49% of the estimated size of chromosomes 21 (48 Mb) and 22 (52 Mb).
