Gas bath capillary tube type micro nucleic acid amplification device

Abstract

The invention discloses a gas bath capillary tube type micro nucleic acid amplification device which comprises a shell. A man-machine interaction panel is arranged at the right end of the shell. A module placing opening is formed in the right side of the shell, a plurality of nucleic acid amplification channel modules are placed in the module placing opening, and the bottom edge of the module placing opening is in pin joint with a thermal baffle. An airflow power source is arranged at the left end of each nucleic acid amplification channel module, and a nucleic acid amplification channel is longitudinally formed in the right side face of each nucleic acid amplification channel module. Each nucleic acid amplification channel module comprises an upper cover and a bottom plate, a heat source is arranged in the center of each bottom plate, a capillary tube support is arranged at the right end of each bottom plate, and a capillary tube is longitudinally placed on each capillary tube support. An airflow treatment module is arranged at the position, between the heat source and the capillary tube, of each bottom plate. The gas bath capillary tube type micro nucleic acid amplification device is relatively simple and low in cost, the amplification procedure of nucleic acid can be screened fast and efficiently, the uniformity of the temperature in the device is guaranteed, and the need for nucleic acid amplification is met.

Description

technical field [0001] The invention relates to the technical field of molecular biology, in particular to an air-bath capillary micro-nucleic acid amplification device. Background technique [0002] At present, the polymerase chain reaction (Polymerase Chain Reaction, PCR) is a kind of technology that a certain DNA segment is copied in a short time in a large amount. This technology generally includes three basic steps of denaturation, annealing and extension. With the continuous cycle of these three basic steps, the specific DNA fragment will grow exponentially, and the amount of a million times that of the reactant can be obtained in a short time. Because PCR technology has the characteristics of strong specificity and high sensitivity, PCR technology has been widely used in the fields of genetically modified product detection, virus detection, drug screening, inspection and quarantine, prevention of agricultural diseases and insect pests, forensic evidence, archaeologica...

AI Technical Summary

Problems solved by technology

The existing temperature-variable metal block and air bath systems control the temperature of multiple samples through overall temperature control. In use, the nucleic acid amplification program cannot be optimally screened, and the uniformity of the temperature inside the system cannot be obtained. ensure

Therefore, it will lead to a lot of time wasted in the nucleic acid amplification process to screen the amplification program and the results are prone to large differences between the reaction tubes in the same amplification.
