20080314751Electrophoretic 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
20090055131AUTOMATIC RECORDING VOLUME MEASUREMENT APPARATUS - Data acquisition apparatus for use with a fluid dispensing device and providing an electronic record of the precise volumes of fluid dispensed from the fluid dispensing device. The fluid dispensing device may be laboratory or clinical apparatus such as an automatic or manual pipette. The apparatus generally includes a fluid volume sensor for detecting the volume of fluid released from the fluid dispensing device and producing electrical signals determined by the volume of fluid released from the device, a data transmission device configured to receive the electrical signals, and a data storage device for storing them.02-26-2009
20090221985SYSTEM FOR IONTOPHORETIC TRANSDERMAL DELIVERY OF POLYMERIC AGENTS AND METHODS OF USE THEREOF - A system for iontophoretic transdermal delivery of a non-peptidic polymeric cosmetic or therapeutic agent or of a polypeptide useful for delivery of high molecular weight cosmetic or therapeutic agents. Particularly, the present invention relates to a system that includes an iontophoresis device and a pharmaceutical composition of a non-peptidic polymeric cosmetic or therapeutic agent together with a peptide, polypeptide or protein and a pharmaceutically acceptable carrier having a pH below or above the isoelectric pH of the peptide, polypeptide or protein.09-03-2009
20100316697METHODS 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
20110112050SEPARATION OF POLYSACCHARIDES BY CHARGE DENSITY GRADIENT - Methods and apparatus for the separation of polysaccharides, particular heparin products, and glycosylated molecules are provided. The separation is based on the molecular weight and charge, by application of an electric field across a low-friction matrix, modified with a charged separation agent comprising charged regions ordered in a monotonous sequence distributed throughout the matrix, to generate a charge density gradient formed when an external electric field is applied. Saccharides of different charges migrate differently across the porous matrix and immobilized by charge neutralization in different charge regions of the matrix.05-12-2011
