Latest Patents
Guy R Cathcart holds a patent for a "Method of nucleic acid extraction." This automated apparatus implements a new method of extracting and purifying nucleic acids from cells without the use of centrifugation. The process involves creating a lysate by treating cells with proteinase K in the presence of a high-salt lysis buffer. The lysate is then mixed with a phenol-based solvent system to create an emulsion, which is heated to promote phase separation. The method enhances phase separation by increasing the surface area of the emulsion. Once phase separation is complete, the lower organic phase is removed, and the upper aqueous phase is extracted multiple times with the phenol-based solvent, followed by chloroform extraction. The remaining aqueous phase is dialyzed to further purify and concentrate the nucleic acid solution. This innovative approach is encapsulated in his single patent.
