Fig. 2From: Saliva samples as a source of DNA for high throughput genotyping: an acceptable and sufficient means in improvement of risk estimation throughout mammographic diagnosticsDNA quality assessment by agarose gel electrophoresis. The quality of extracted DNA was analyzed by agarose gel electrophoresis. Three microlitres of each DNA sample (number 1–64) was loaded onto a 2% agarose gel. The first lane shows lambda DNA (300 ng), which was used as a high-quality control, followed by the isolated DNA samplesBack to article page
