A solid-phase method for preparing human DNA from urine for diagnostic purposes
چکیده انگلیسی

ObjectivesTo develop a simple method using paramagnetic beads for isolation of human DNA from small volumes of urine. The method should be amendable for automation. The purified DNA is intended to be used in downstream diagnostics and screening studies using nucleic acid amplification techniques.Design and methodsUnspecific capture of cells present in urine to magnetic particles, lysis and subsequent binding of the DNA to the same bead surface.ResultsDNA isolated using the method could be used as template for sensitive real-time PCR and end-point PCR using primers targeted to the GAPDH, K-ras, DD3 and p53 genes. Compared to silica spin column-based extraction, the method showed equal or higher DNA yields. The method performed reliably when automated using a liquid handling robot equipped with a magnetic workstation.ConclusionsThe method generates purified DNA free from inhibitors, applicable for sensitive applications such as real-time PCR, genotyping, and for sequence variant analysis. The use of magnetic beads allows for automation, reducing hands-on time and creating a high throughput and reproducible protocol for the purpose of large-scale screening and diagnostics.
