| 20100089755 | Technical measure for gel electrophoresis shaping - A technical measure for gel electrophoresis shaping that can make the gel electrophoresis generate no bubbles including in the gel, and can make a gradient gel being more accurate and more stable in quality. When liquid gel enters a collecting trough under continuous driving of a roller in the collecting trough to be injected into a carrier sheet set from a gel output port and a narrow seam, former injected liquid gel can be pushed upwards by latter injected liquid gel, and an accomplished product of gel can be obtained. If the collecting trough is input with two liquid basic materials, the liquid gel continuously output into the carrier sheet set can have a gradient. | 04-15-2010 |
| 20100326829 | MONOLITHIC ELECTROPHORESIS GEL SYSTEM - Apparatus, systems and methods for performing gel electrophoresis using a monolithic electrophoresis unit that at least includes first and second chambers containing one or more buffer solutions and a gel chamber containing a pre-cast gel, whereby all of these chambers are integrated into a pre-fabricated single unit that is ready for use. In performing gel electrophoresis, a top seal of this monolithic electrophoresis unit is removed, followed by optionally removing a gel chamber seal from over the gel chamber, such that, buffer solution contacts the pre-cast gel within the gel chamber. Target samples are loaded into the gel chamber for contact with the pre-cast gel, a reusable lid is attached to the top surface of the monolithic electrophoresis unit, and an electrical connection is provided through the reusable lid into the monolithic electrophoresis unit for performing electrophoresis on the pre-cast gel. | 12-30-2010 |
| 20110220503 | ELECTROKINETIC PUMPING OF NONPOLAR SOLVENTS USING IONIC FLUID - Techniques are generally described that include electrokinetic pumping an emulsion comprising an ionic fluid and a nonpolar fluid to promote flow of the ionic fluid by electro-osmotic flow and drag the nonpolar fluid by viscous drag forces. In some examples, the electrokinetic pump may be utilized to deliver one or more reagents within a fluidic reactor system, such as a micro-scale reactor system. In some additional examples, a reagent may be dissolved in the nonpolar fluid of a first emulsion and pumped through the electrokinetic pump to a mixing channel to allow the reagent of the first emulsion to react with a reagent of second emulsion to form a reactive product. | 09-15-2011 |
| 20120055794 | MONOLITHIC ELECTROPHORESIS FLAT GEL SYSTEM - Apparatus, systems and methods for performing gel electrophoresis using a horizontal monolithic electrophoresis unit that at least includes first and second buffer chambers containing buffer solution and a gel chamber containing a pre-cast flat gel, whereby all of these chambers are integrated into a pre-fabricated single unit that is ready for use. In performing gel electrophoresis, a top seal of this monolithic electrophoresis unit is removed, target samples are loaded into the pre-cast gel, interior walls of the unit are broken to allow buffer from anode and cathode chambers to combine within the gel chamber and cover the loaded gel matrix, a reusable lid is attached to the top surface of the unit, and an electrical connection is provided through the reusable lid into the horizontal monolithic electrophoresis unit for performing electrophoresis on the flat pre-cast gel. | 03-08-2012 |
| 20120097540 | MATERIALS AND METHODS FOR RESOLVING POLYHYDRIC SPECIES BY ELECTROPHORESIS - Materials and methods employing a polymerisable boronic acid species and a polymerisable linker are disclosed for making gels for resolving polyhydric species present in a sample by electrophoresis. The electrophoresis gels are capable of improving the effective separation of polyhydric species, especially those that show similar mobilities in standard electrophoresis or fluorophore-assisted carbohydrate electrophoresis (FACE). The use of template molecules in the reaction to form the electrophoresis gel with the boronic acid species and the polymerisable linker, so that the template molecule becomes incorporated into the electrophoresis gel, is also disclosed. The template molecule provides cavities in the electrophoresis gel that are generally complementary to the template molecule and which are adapted to reversibly interact with one or more of the polyhydric species present in the sample that have structures similar to the template molecule. | 04-26-2012 |
| 20140251809 | APPARATUS FOR PREPARING NUCLEIC ACIDS AND METHOD FOR PREPARING NUCLEIC ACIDS - An apparatus for preparing nucleic acids is provided which includes an anode, a cathode, and a space formed between the anode and the cathode. In addition, in the apparatus described above, the space includes a first porous film provided at an anode side, a second porous film provided at a cathode side, an inlet port which is proved in a region sandwiched between the first porous film and the second porous film and which introduces a specimen containing proteins and nucleic acids into the region, and a gel filter provided between the inlet port and the first porous film. | 09-11-2014 |
| 20150323496 | Integrated Droplet Actuator for Gel Electrophoresis and Molecular Analysis - The invention is directed to a droplet actuator device and methods for integrating gel electrophoresis analysis with pre or post-analytical sample handling as well as other molecular analysis processes. Using digital microfluidics technology, the droplet actuator device and methods of the invention provide the ability to perform gel electrophoresis and liquid handling operations on a single integrated device. The integrated liquid handling operations may be used to prepare and deliver samples to the electrophoresis gel, capture and subsequently process products of the electrophoresis gel or perform additional assays on the same sample materials which are analyzed by gel electrophoresis. In one embodiment, one or more molecular assays, such as nucleic acid (e.g., DNA) quantification by real-time PCR, and one or more sample processing operations such as sample dilution is performed on a droplet actuator integrated with an electrophoresis gel. In one embodiment, an electrophoresis gel may be integrated on the top substrate of the droplet actuator. | 11-12-2015 |
