Abstract

The analysis of genomic DNA is widely-used for research, forensic and diagnostic purposes. Here we describe reliable methods for isolation of cell-free DNA and cellular DNA from urine. Both DNA fractions are suitable for PCR and Methylation-Specific PCR (MSP) amplification, leading to consistent and reproducible results. A kinetics analysis de- scribes the decline of efficiency of MSP performed with urinary DNA which had been stored at room temperature with and without proteinase K for various time periods.

分离尿中游离DNA和细胞DNA的方法——甲基化特异性PCR在两种DNA片段上的应用

基因组DNA的分析被广泛用于研究、法医和诊断目的。在这里，我们描述了从尿液中分离无细胞DNA和细胞DNA的可靠方法。这两个DNA片段都适用于PCR和甲基化特异性PCR (MSP)扩增，导致一致和可重复的结果。动力学分析描述了在室温下储存不同时间的有或没有蛋白酶K的尿液DNA进行MSP效率的下降。
