![]() Physical methods are often used with more structured input materials, such as tissues or plants. Grinders can be simple manual devices or automated, capable of disruption of multiple 96-well plates. A common method of physical disruption is freezing and grinding samples with a mortar and pestle under liquid nitrogen to provide a powdered material that is then exposed to chemical or enzymatic lysis conditions. Physical methods typically involve some type of sample grinding or crushing to disrupt the cell walls or tough tissue. ![]() There are four general techniques for lysing materials: physical methods, enzymatic methods, chemical methods and combinations of the three. The goal of lysis is to rapidly and completely disrupt cells in a sample to release nucleic acid into the lysate. The first step in any nucleic acid purification reaction is releasing the DNA/RNA into solution.
