20120164633 | DIGITAL DROPLET SEQUENCING - The present invention provides systems, devices, methods, kits, and compositions for sorting and analysis of nucleic acid sequences using digital droplet PCR. In particular, provided herein are methods to convert complex samples into a plurality of simplified samples, and sequence analysis thereof. | 06-28-2012 |
20130183717 | CHANNELS WITH CROSS-SECTIONAL THERMAL GRADIENTS - Provided herein are systems, devices, and methods for generating thermal gradients in channels and uses thereof. In particular, provided herein are system, methods, and devices employing first and second thermal layers positioned around a channel in order to create a thermal gradient across a cross-section of the channel having, for example, a nucleic acid denaturation zone, a nucleic acid annealing zone, and a nucleic acid polymerization zone. Such devices find use in, for example, nucleic acid amplification procedures, including digital polymerase chain reaction (dPCR) to temperature cycle droplets for amplification of nucleic acid templates within the droplets. | 07-18-2013 |
20130184446 | MICROORGANISM NUCLEIC ACID PURIFICATION FROM HOST SAMPLES - The present disclosure provides systems, devices, and methods for purifying microorganism nucleic acid from a host sample, such as a whole blood sample from a human. In certain embodiments, devices and systems with multiple filters are employed and provide for the selective removal of blood cells and host nucleic acids from a sample in order to enrich for microorganism nucleic acid. | 07-18-2013 |
20130323815 | FUNGAL NUCLEIC ACID EXTRACTION - The invention provides methods for extraction of fungal (e.g., yeast spp., filamentous fungal spp.) nucleic acid (e.g., DNA, RNA) from a sample (e.g., be human or veterinary clinical or research samples, agricultural samples, agricultural commodity samples, food products, or environmental samples). In some embodiments, the present invention provides enhanced nucleic acid extraction from samples comprising fungal cell(s) wherein enzymatic (e.g., lysostaphin treatment, lyticase treatment) sample treatment is performed in combination with mechanical (e.g., bead beating) sample treatment. | 12-05-2013 |
