AI summary

The invention utilizes a single Cloudy-Precipitated Buffer solution (CP Solution) for extracting biomolecules, including nucleic acids. The CP Solution remains cloudy even when heated, becoming clear only with the addition of organic solvents. It can be used in its cloudy state in both One-Step-Method and Multiple-Steps-Method, collectively referred to as OM Method. OM Method involves treating samples with various buffer compositions under optimized conditions, available as a kit. The CP Solution, containing anionic, cationic, and non-ionic detergents, chaotropic agents, alcohols, salts, oils, adsorbents, and organic solvents, does not require heating or organic solvents to clear. It effectively lyses cells and extracts nucleic acids without the need for multiple buffers or additional chemicals. This innovation reduces costs, labor, time, and errors, while minimizing pollution. The invention includes various buffer compositions for nucleic acid extraction and a corresponding kit, addressing current extraction process challenges.
