DNA extraction kits are used to isolate DNA from a sample. These kits are widely used in molecular biology research and diagnostics. The most common method used by these kits is the silica spin filter method.The silica spin filter method is fast, efficient, and produces high-quality DNA suitable for downstream applications such as PCR, sequencing, or cloning 12. However, it’s important to note that while these kits make the process much easier and faster than traditional methods of DNA isolation, it’s still important to understand how they work in order to troubleshoot any issues that may arise
