Latest Patents

David L Roerig holds a patent for a method of preparative, Kohlrausch-regulated electrophoresis. This improved method focuses on the preparative separation of macromolecular components, such as proteins, from crude samples. The technique utilizes a substantially linear, polyethylene glycol derivatized trailing ion, which has a high mass to charge ratio and low mobility that remains stable across a broad pH range. The most preferred trailing ion is a polyethylene glycol dicarboxylic acid with a molecular weight of about 6,000-7,500, a pKa value of approximately 3.7, and a fully ionized mobility of about -1.3 × 10^-5 cm²/volt/sec. This innovative method allows for large-scale protein separations and the collection of purified protein fractions without interference from reactions between the proteins and the trailing ion. David L Roerig has 1 patent to his name.
