20120289421 | Method and Apparatus for High Accuracy Genomic Analysis Platform Utilizing Hybridization and Enhanced Dissociation - Methods and an apparatus according to the present invention, can be used in capture/enrichment, gene expression profiling and targeted sequencing. Provided are methods for improving accuracy and stringency of microarrays and/or other genomic analysis methods relying on nucleic acid hybridization and melting curve analysis by controlling surface chemistry. This method comprises producing a positively charged surface or surface coating, on the surface of microarray slides or other types of surfaces similarly purposed, such as micro beads, which enhances melting curve analysis to the point of allowing detection or differentiation of small changes in sequences between nucleic acid binding partners. Also provided is an improved microarray reader machine, to collect melting curve data on microarray slides. The accuracy or resolution of melting curve analysis was to be sufficient to distinguish between the melting of perfect matched dsDNA and dsDNA with the smallest possible change in sequence, a one base pair mismatch. | 11-15-2012 |
20110111968 | Method and Apparatus for Melting Curve Analysis of Nucleic Acids in Microarray Format - A method and apparatus for performing melting curve analyses of nucleic acids on a microarray is described. The present method includes varying the temperature of a fluid on a microarray to dissociate and remove target DNA, scanning the mircoarray for fluorescence, collecting the target DNA removed from the microarray, and reusing the collected target DNA and the microarray. The apparatus of the present disclosure includes a microarray stage, a light source and detector, and a temperature controller, wherein the temperature controller is configured to adjust the temperature of a fluid within a sample chamber on the microarray such that the temperature of the fluid is varied during the analysis such that target DNA is dissociated from the microarray, and wherein the light source is directed to the microarray and the resulting fluorescence is perceived by the detector. | 05-12-2011 |
