Each sample was briefly minced in two buffers, Tris-EDTA (TE) or PCR buffer, and A number of factors play a role in the quality and quantity of extracted DNA in a given sample including growth time of the cultures (which when extended to months results in the presence of dead cells and likely degraded DNA), duration and temperature of heat kill when that is required, storage of pellets before extraction, and reagents and High pressure keeps solvents in a liquid state above their boiling point resulting in a high solubility and high diffusion rate of lipid solutes in the solvent, and a high penetration of the solvent in the matrix. Shaking too hard will shear the DNA. microwave based method other methods are not shown. Thus, the appropriate concentration of MgOAc enhances the enzyme-catalyzed amplification process.
