Used in molecular biology for the isolation and purification of nucleic acids, particularly DNA, from various biological samples. Effective in breaking down cell membranes and nuclear envelopes due to its strong detergent properties, allowing efficient release of genomic DNA. Commonly used in plant, bacterial, and fungal DNA extraction protocols where high molecular weight and purity are required. Helps separate DNA from proteins and polysaccharides by forming complexes with cellular debris, which can be removed via centrifugation. Ideal for downstream applications such as PCR, restriction digestion, and sequencing due to the high quality of extracted DNA.
