检测人类基因组DNA有许多分子生物学技术,诸如PCR、RFLP、SSCP、微卫星技术和测序技术等,各有优缺点。为了显示和观察结果,也曾采用多种方法,如EB染色、银染色、同位素或荧光显示,也各有其优缺点。我们采用的改良DNA银染色法,具有操作简单、快速,敏感性较高,毒性小和价格便宜等 There are many molecular biology techniques used to detect human genomic DNA, such as PCR, RFLP, SSCP, microsatellite and sequencing technologies, each with its own advantages and disadvantages. In order to display and observe the results, a variety of methods have also been used, such as EB staining, silver staining, isotope or fluorescence display, also have their advantages and disadvantages. We use the improved DNA silver staining, with simple, fast, high sensitivity, low toxicity and cheap
