Used primarily in molecular biology for the isolation and purification of nucleic acids. It aids in cell lysis by disrupting cell membranes and denaturing proteins, ensuring the release of DNA or RNA. Commonly employed in protocols for extracting high-purity DNA, such as in plasmid preparation or genomic DNA isolation. It is also utilized in gel electrophoresis as a detergent to maintain protein solubility and impart a uniform negative charge for separation. Its high purity ensures minimal interference with downstream applications like PCR, sequencing, or cloning.
