Title: The Innovations of Richard G. Hatch
Introduction
Richard G. Hatch is a notable inventor based in Berkeley, CA, with a significant contribution to the field of biotechnology. He holds a total of 5 patents, showcasing his innovative approach to solving complex scientific problems. His work primarily focuses on methods for separating macromolecules and enhancing liquid chromatography techniques.
Latest Patents
One of his latest patents is titled "Method of detecting sequence variations in macromolecules by thermal gradient." This invention describes a method for separating macromolecules, particularly heteroduplex from homoduplex DNA molecules. The process involves a temperature-sensitive structural denaturation that results in a difference in the mobilities of the denatured components on a solid support. Notably, this method does not require a polar to non-polar solvent gradient or a modified solid support, as the difference in mobility is achieved using a single mobile phase composition on conventional solid supports.
Another significant patent by Hatch is the "Monolithic matrix for separating bio-organic molecules." This invention provides monolithic polymer matrices for the separation of bio-organic molecules by liquid chromatography. In one embodiment, the matrix is formed from a polymerization mixture that includes a hydrophobic monomer, a crosslinking agent, and a porogenic solvent or mixture of porogenic components. These monolithic matrices are particularly useful for resolving polynucleotides, such as DNA and RNA, in samples through reversed-phase ion-pairing chromatography.
