| 20080314751 | Electrophoretic Separation of Analytes by Molecular Mass - The present invention relates to a method and apparatus for the separation of analytes based on their molecular weight, by application of an electric field across a low-friction matrix that includes with a charged separation agent. The matrix comprises charged regions ordered in a monotonous sequence distributed throughout the matrix so as to generate a charge density gradient. When an external electric field is applied, the complex will move through the different charged regions and focusing of different analytes in different charge regions will occur. These systems are suitable for planar, capillary in-tube electrophoresis, as well as multi-channel arrays of capillaries filled with charge gradient gels, serial arrays of discrete compartments with charge density gradient, arrays in a chip format, pre-designed mass focusing arrays for specific protein masses in application for protein and DNA marker diagnostics, and multi compartment trapping devices for specific mass ranges. | 12-25-2008 |

| 20100316697 | METHODS AND COMPOSITIONS FOR DRUG TARGETING - The present invention provides methods and compositions for targeting a drug to a specific desired location, such as an intracellular location in a mammalian cell, by causing said drug to migrate along a pH gradient to the specific location, where the drug preferentially accumulates at a pH range of the specific location. Accordingly, the invention described herein is based on providing a drug which is “pH matched” with that of a particular location, such that the drug preferentially migrates to and accumulates at the pH or pH range at that location. The location may be a type of tissue, a type of cell, a sub-cellular location or an intracellular location, such as an organelle. Without being bound to any theory, the drug migrates along or across a pH gradient, and stops migrating and accumulates at a location of specific pH or range of pH at which the drug is energetically neutral, or where its diffusion potential is at a minimum. | 12-16-2010 |
| 20110112050 | SEPARATION OF POLYSACCHARIDES BY CHARGE DENSITY GRADIENT - Methods and apparatus for the separation of polysaccharides, particular heparin products, and glycosylated molecules are provided.
