Compositions and kits are also provided. | 09-23-2010 |
| 20100233704 | METHODS OF DETECTING LUNG CANCER - Methods of lung cancer in a sample from a patient are provided. Methods of detecting changes in expression of one or more target RNAs associated with lung cancer are also provided. Compositions and kits are also provided. | 09-16-2010 |
| 20100136569 | COMPOSITIONS, METHODS AND KITS FOR POLYNUCLEOTIDE AMPLIFICATION REACTIONS AND MICROFLUIDIC DEVICES - Antifoam agents improve detection of polynucleotide amplification reactions and improve manipulation of fluids in microfluidic devices. | 06-03-2010 |
| 20100129827 | METHOD AND DEVICE FOR SAMPLE PREPARATION CONTROL - A method for preparing a sample suspected to contain a target nucleic acid sequence for a nucleic acid amplification reaction and for verifying the effectiveness of the sample preparation comprises the step of mixing the sample with sample preparation controls. The sample preparation controls are cells, spores, microorganisms, or viruses that contain a marker nucleic acid sequence. The sample mixed with the sample preparation controls is subjected to a lysis treatment, and nucleic acid released by the lysis treatment is subjected to nucleic acid amplification conditions. The presence or absence of the target nucleic acid sequence and of the marker nucleic acid sequence is then determined. Positive detection of the marker nucleic acid sequence indicates that the sample preparation process was satisfactory, while the inability to detect the marker nucleic acid sequence indicates inadequate sample preparation. | 05-27-2010 |
| 20100068706 | METHOD FOR SEPARATING AN ANALYTE FROM A SAMPLE - An analyte is separated from a fluid sample by introducing the sample into a cartridge having a sample port and a first flow path extending from the sample port. The first flow path includes an extraction chamber containing a solid support for capturing the analyte from the sample. The cartridge has a second flow path for eluting the captured analyte from the extraction chamber, the second flow diverging from the first flow path after passing through the extraction chamber. The sample is forced to flow through the extraction chamber and into a waste chamber, thereby capturing the analyte with the solid support as the sample flows through the extraction chamber. The captured analyte is then eluted from the extraction chamber by forcing an elution fluid to flow through the extraction chamber and along the second flow path. | 03-18-2010 |
| 20090308886 | METHOD AND APPARATUS FOR STORING AND DISPENSING REAGENT BEADS - Embodiments of the invention provide an efficient and effective technique for storing and dispensing reagent beads. In some embodiments, an apparatus is provided for dispensing reagent beads contained in a bead storage device which includes a bead carrier having a plurality of wells; a plurality of reagent beads disposed in the wells; and a cover tape releasably attached to the bead carrier to cover the wells and retain the reagent beads in the wells. The apparatus comprises a channel in which to place the bead storage device with the bead carrier facing a support wall of the channel and the cover tape facing a stripping wall of the channel. The stripping wall includes a stripping gap disposed between a stripping edge and an opposite edge, and a dispense opening provided adjacent the opposite edge on a side of the stripping wall opposite from the stripping edge. The cover tape is insertable through the stripping gap to be pulled against the stripping edge to peel the cover tape from the bead carrier to move the wells of the bead carrier inside the channel toward the dispense opening and expose the wells individually to dispense the reagent beads. | 12-17-2009 |
