DNA-Grade 75% Ethanol is used in molecular biology for washing precipitated nucleic acids during DNA and RNA extraction protocols. It removes residual impurities such as salts, proteins, and other contaminants without solubilizing the nucleic acid pellet, thereby preserving integrity and enhancing purity. Commonly applied in post-centrifugation washing steps. This high-purity formulation is stable at room temperature, compatible with automated systems and standard lab protocols, and free from nucleases, endotoxins, and other inhibitors. It ensures high yield and purity essential for downstream applications including PCR, sequencing, and cloning.
