| 20110306511 | METHODS FOR MULTIPLEX ANALYTE DETECTION AND QUANTIFICATION - The application refers to a method for detecting and quantifying multiple target analytes in a test sample using a single reaction vessel. The method uses a reaction vessel (a multi-well plate), which comprises a microarray of: (a) calibration spots, each having a predetermined quantity of the target analyte; and (b) capture spots, each having an agent (antibody) that selectively binds the target analyte. The captured analytes and the calibration spots are detected with fluorescently labelled antibodies specific for each different target analyte. The calibration spots are used to generate calibration curves that allow the measurement of the concentration of the different target analytes. The application also refers to a method for detecting and quantifying biomarkers that are useful for diagnosing rheumatoid arthritis. More specifically, the application discloses the use of rheumatoid factor (RF) and cyclic citrullinated peptide (CCP), as capture spots. Finally, based on the above method, it is proposed a method for diagnosing or monitoring rheumatoid arthritis. | 12-15-2011 |
| 20110281028 | Method for double-dip substrate spin optimization of coated micro array supports - Described is a method for preparing a substrate-coated support for use in micro-array devices. The method comprises the steps of applying a first coat of substrate to a support, making the substrate coating ramp by subjecting the coated support to centripetal forces, adding a second coat of substrate to the resulting support having a ramping planar coat, and subjecting the coated support to centripetal forces for a second time to produce a substrate-coated membrane in which the thickness of the substrate layer is uniform across the entire coated surface. | 11-17-2011 |
| 20110247410 | METHOD FOR MEASURING AND/OR TESTING WAVINESS OF A PLANAR TEXTILE - The invention relates to a method for measuring and/or testing a geometric design parameter, particularly waviness, of a planar textile ( | 10-13-2011 |
| 20110232125 | METHOD AND DEVICE TO REMOVE FLUID AND VAPOR - The present invention relates to a method and device for the removal of fluids and vapors in containment, from adjacent surfaces including supporting flat surfaces and substrates, such as protein spots printed in arrays and micro-array formats. This method and device removes fluids and vapors under controlled and repeatable conditions, enabling uniform phases for degree of drying incurred by objects, specimen and structures, including tissues, adsorbed particles and biological substrates, while reducing and preventing impact of meniscus phase surface tension forces. | 09-29-2011 |
| 20110201522 | ARRAY FLUORESCENCE EQUALIZATION METHOD - The present invention provides a method for fluorescence intensity equalization. The method involves providing an assay device having at least one immobilized array of molecular probes that bind to an analyte bound to a fluorescent marker; providing drying apparatus comprising an aspiration tube having open first and second ends, the second end of the aspiration tube being connected a vacuum source for applying a vacuum through said tube; placing the first end of the aspiration tube in proximity of said at least one immobilized array of molecular probes; and applying a vacuum through said aspiration tube for removing vapor from said at least one immobilized array of molecular probes. The application of the present invention provides for more reliable fluorescent signal intensity readings due to a reduction in signal quenching factors. | 08-18-2011 |
