DNA extraction is crucial for acquiring an initial sample for techniques such as PCR, DNA sequencing, and electrophoresis. However, these processes require a high yield and the removal of impurities (such as cell debris) to successfully provide truthful findings. For example, the presence of contaminants such as DNases can lead to the breakdown of DNA and so reduce the overall yield, potentially below the required sample amount.
This video will help optimize your DNA extraction technique, clearly explaining and offering tips on how to achieve efficient, reliable results; avoiding contamination and poor yield.
