20100025244 | Assay for species sources - A family of PCR assays is disclosed for determining, both qualitatively and quantitatively, presence of material from a predetermined species source and for quantifying the amount of such material. The assays are based respectively on SINEs uniquely characteristic of pig species, cow species, chicken species, and ruminant sub-order, and having a high copy number. The assays disclosed permit rapid, inexpensive evaluation of meat samples to facilitate elimination from their diet of pork or beef by persons desiring to avoid such food sources; as well as the assay of cattle feed to determine presence therein of ruminant-source proteins, which are a potential source of bovine spongiform encephalopathy (BSE), commonly referred to as “mad cow disease.” The assays amplify the predetermined unique SINEs and the resulting amplified mixture is then evaluated qualitatively by electrophoresis on gel containing ethidium bromide or quantitatively by SYBR Green-based detection or TaqMan chemistry. The invention also extends to kits, primers, and other products used in connection with the assays. The amplicons are selected to be from about 100 to 170 bp long. | 02-04-2010 |
20100126862 | MULTICHANNEL PREPARATIVE ELECTROPHORESIS SYSTEM - The invention provides an electrophoresis cassette, methods for making the electrophoresis cassette, and method of fractionating analytes from a sample based upon electrophoretic mobility in a single application of the sample to an electrophoretic system. | 05-27-2010 |
20100126863 | System and method for fully automated two dimensional gel electrophoresis - A new approach is proposed that contemplates systems and methods to support a fully automated two dimensional gel electrophoresis instrument with modular scalability to support laboratory needs. Each instrument integrates a plurality of “plug-n-play” removable all-in-one precast “unigel” cassettes that each houses one or more of first and second dimension gels casted on a gel supports, wherein the cassette capacities of the instrument can be expanded to accommodate increasing numbers of cassettes. Here, each of the cassettes integrates a first dimension gel unit of the isoelectric focusing process and a second dimension gel unit of the polyacrylamide gel electrophoresis process and allows for automatic insertion, removal, cooling, staining and distaining of the gels as well as addition of samples and operational buffers. | 05-27-2010 |
20110062024 | MULTICHANNEL PREPARATIVE ELECTROPHORESIS SYSTEM - The invention provides an electrophoresis cassette, methods for making the electrophoresis cassette, and method of fractionating analytes from a sample based upon electrophoretic mobility in a single application of the sample to an electrophoretic system. | 03-17-2011 |
20110220501 | Programmable Electrophoretic Notch Filter Systems and Methods - An electrophoretic notch filter apparatus including a gel cartridge having at least one sample channel, an electrode and a counter electrode each engagable with the sample channel, a user interface for programming one or more steps for a sample channel into a processor to form a programmed sequence and an electrophoretic controller for implementing the programmed sequence. | 09-15-2011 |
20110220502 | Unitary Biochip Providing Sample-in to Results-out Processing and Methods of Manufacture - A biochip for the integration of all steps in a complex process from the insertion of a sample to the generation of a result, performed without operator intervention includes microfluidic and macrofluidic features that are acted on by instrument subsystems in a series of scripted processing steps. Methods for fabricating these complex biochips of high feature density by injection molding are also provided. | 09-15-2011 |
20120103811 | PROTEIN MULTI-BLOTTING METHOD AND DEVICE - A technique for producing multiple protein blots from a single gel, including entering the number ‘n’ membranes to be blotted into microprocessor memory, determining calibration constants for a gel batch, inputting calibration constants into microprocessor memory, and calculating ‘n’ voltage/time profiles for simultaneous blotting. A gel layer from the gel batch is treated with a protein sample, ‘n’ membranes are placed onto the gel layer to yield a gel pack, and the gel pack is placed between an electrode plate maintained at a fixed first voltage and an array of ‘n’ spaced generally parallel electrodes. The voltage to each respective ‘n’ spaced generally parallel electrodes is varied over time according to a respective ‘n’ voltage/time profile to transfer proteins to each respective ‘n’ membranes to yield blotted membranes to yield ‘n’ respective blotted membranes. | 05-03-2012 |

20090014332 | Fractionation of Macro-Molecules Using Asymmetric Pulsed Field Electrophoresis - A method and apparatus for fractionation of charged macro-molecules such as DNA is provided. DNA solution is loaded into a matrix including an array of obstacles. An alternating electric field having two different fields at different orientations is applied. The alternating electric field is asymmetric in that one field is stronger in duration or intensity than the other field, or is otherwise asymmetric. The DNA molecules are thereby fractionated according to site and are driven to a far side of the matrix where the fractionated DNA is recovered. The fractionating electric field can be used to load and recover the DNA to operate the process continuously. | 01-15-2009 |
