摘要:
A method of amplifying nucleic acid from blood, the method including performing an electrodialysis on a blood sample to reduce the ionic strength of the sample, and performing a Polymerase Chain Reaction (“PCR”) using the blood sample on which the electrodialysis is performed as a template.
摘要:
A method of isolating nucleic acid from a sample containing nucleic acid is provided. The method includes contacting the sample with a bifunctional material that contains an amino group and a carboxyl group and is positively charged at a first pH to allow binding of the nucleic acid to the bifunctional material; and extracting the nucleic acid at a second pH higher than the first pH from the complex.
摘要:
A method of lysing at least one of a cell and a virus, the method including: contacting a sample, which includes at least one of a cell and a virus, with a plurality of beads which are disposed in a first chamber to obtain a combination of the sample and the beads; and agitating the combination of the sample and the beads to lyse the at least one of the cell and the virus, wherein in the first chamber a liquid volume fraction is 0.6 or less, and wherein the liquid volume fraction is a value obtained by dividing a liquid volume of the first chamber by a pure void volume equivalent to a sum of the liquid volume of the first chamber and a void volume of the first chamber.
摘要:
Provided is a method of amplifying nucleic acid from a comprising: contacting a cell-containing sample with a nonplanar solid substrate in a liquid medium having a pH range of 3.0-6.0 to attach the cell to the solid substrate; washing the nonplanar solid substrate to remove materials that are not attached thereto; and performing PCR using the nucleic acid from the cell attached to the nonplanar solid substrate as a template sample to amplify nucleic acid from the cell, wherein the contacting, washing and PCR processes are performed in a single vessel.
摘要:
A gene analysis apparatus includes a sample preparation chip in which a polymerase chain reaction (“PCR”) sample is prepared, a PCR chip in which a PCR is performed on the PCR sample, and a package layer on which the sample preparation chip and the PCR chip are mounted. The package layer includes a channel through which a material flows from the sample preparation chip to the PCR chip. The sample preparation chip and the PCR chip are on a same side or on opposing sides of the package layer.
摘要:
A micro-device for disrupting cells includes a first chamber in which the cells are disrupted, a second chamber which is pressurized and depressurized, a flexible membrane which separates the first chamber and the second chamber and is vibrated by pressuring and depressurizing the second chamber, and a micro-unit confined in the first chamber, where the micro-unit disrupts the cells in the first chamber.
摘要:
Provided is a method of separating microorganisms from a sample including contacting the sample containing microorganisms with an inorganic on exchange material such that the sample reacts with the inorganic on exchange material, and contacting the reacted sample with a means for capturing microorganisms.
