Nucleic acid extraction instrument and nucleic acid extraction method

Abstract

The invention provides a nucleic acid extraction instrument and a nucleic acid extraction method, which can improve the automation degree and is beneficial to reducing the cost. The nucleic acid extraction instrument comprises a bracket, a containing table, a first position sensor assembly, a camera, a label identification device and a controller, the accommodating table is used for accommodating the deep hole plate; a sample label is arranged on the side surface of the deep-hole plate and is used for indicating information of a sample associated with the deep-hole plate; the first position sensor assembly is used for sensing whether the deep hole plate is accommodated in place or not; when the deep hole plate is accommodated in place, the sample label is aligned with a light inlet of the camera, and the camera is used for collecting an image containing the sample label; the label identification device is used for receiving the image and identifying a sample label in the image; the controller is used for receiving the recognition result, determining the category of the sample based on the recognition result, and obtaining a target nucleic acid extraction program corresponding to the category of the sample from a plurality of stored nucleic acid extraction programs, and the target nucleic acid extraction program is used for realizing nucleic acid extraction of the sample.

Description

technical field [0001] The invention relates to the technical field of nucleic acid extraction, in particular to a nucleic acid extraction instrument and a nucleic acid extraction method. Background technique [0002] Nucleic acid extraction technology is an important method to achieve precision medicine in the fields of biology and medicine. In order to avoid sample contamination and save labor costs, traditional manual experimental extraction has been gradually replaced by automated nucleic acid extraction, that is, automated nucleic acid extraction can be achieved through pre-set nucleic acid extraction procedures. [0003] Although nucleic acid extraction can be achieved through nucleic acid extraction procedures, a series of other work is required before this, including the selection of procedures. In the current relevant nucleic acid extraction experiments, the experimenter records the sample information and marks the deep-well plate in advance, then puts the deep-wel...

Problems solved by technology

[0004] In the above method, the entire experimental process is not completely automated, which is more labor-intensive and time-consuming, especially if there are many nucleic acid extraction procedures, such as when the nucleic acid extraction instrument has 500 programs stored in advance, the experimenter manually selects the nucleic acid The extraction procedure will be a particularly cumbersome process
