PrefaceCell free DNA (cfDNA) is becoming increasingly prominent as a novel molecular marker for disease prediction and tumor prevention. However, there are still many obstacles before achieving its widespread clinical application, mainly the lack of standards related to cfDNA, resulting in the lack

The extraction of nucleic acid using magnetic beads is still a relatively new nucleic acid extraction method, compared with the traditional chloroform isoamyl alcohol extraction method and spin column kit method. This method is still not understood well by many people, and there are some misundersta

1. Introduction to nucleic acid extraction and purificationNucleic acid extraction is a basic part of molecular biology, because high-quality nucleic acid is essential for molecular biology applications.We will summarize some of the currently used nucleic acid extraction techniques and tips on choos
