Abstract:
A method of analyzing nucleic acid by compensating for crosstalk in polymerase chain reaction (PCR) data and other data, wherein crosstalk signals associated with multiple fluorescent dyes are corrected by using fluorescent intensity variations detected from a concentration difference of the fluorescent dyes, and apparatus for performing the method.
Abstract:
A reagent supply device includes a plurality of chambers which are separated from each other such that different reagents may be injected, the plurality of chambers having bottom surfaces made of a membrane, the membrane comprising a destruction pattern which is formed at a position corresponding to each of the plurality of chambers and breachable by an external impact to discharge the injected reagent from the chamber.
Abstract:
A method and apparatus for performing quantitative analysis of a nucleic acid by determining a curve-fitting area based on fluorescence intensity data obtained by performing PCR on a target nucleic acid; analyzing parameters for amplification efficiency and nucleic acid concentration by curve-fitting a result of performing PCR on a reference nucleic acid with a known initial nucleic acid concentration; and estimating the initial nucleic acid concentration of the target nucleic acid by performing curve-fitting on the determined curve-fitting area using the analyzed parameters.
Abstract:
A fluid control apparatus including a detecting unit including a light source for irradiating light toward a microfluidic device, and a photodetector for detecting light reflected from the microfluidic device, a transporting unit for moving the detecting unit; and a determining unit for controlling a transporting operation by the transporting unit, where determining a state of a fluid at a particular position relative to the microfluidic device is based on light reflected from the microfluidic device, and method of using same.
Abstract:
A method of compressing and storing data may include generating target code words by compressing target data to be stored in a memory device by using an initially set compression algorithm; and/or storing in the memory device the target code words according to a data pattern that is repeated in the target code words. A method of compressing and storing data may include generating target code words by compressing target data to be stored in a memory device by using an initially set compression algorithm; and/or storing in the memory device delta-encoded information obtained by performing delta-encoding on the target code words based on source code words including the data pattern.
Abstract:
A method of managing a storage region of a memory device, and a storage apparatus using the method. In the method, data blocks are arranged in an order of performing writing on the memory device; a frequency of updating data in a logical page to be written is determined, based on whether an invalid physical page is present in a block within a window size that is initially set based on a most recently written data block from among the arranged data blocks, in response to a write request, and the data in the logical page is stored in a storage region of the memory device classified according to the determined frequency, according to the determined frequency.
