Sample processing system

Abstract

The invention discloses a sample processing system. The sample processing system comprises: a processing device, wherein the processing device comprises a mounting baseboard, the mounting baseboard isprovided with a sample extraction area and a PCR reaction area, the sample extraction area can perform DNA extraction on a sample, and the PCR reaction area can perform a PCR reaction on the extracted DNA; and a pipetting device, wherein the pipetting device includes a support frame, a moving device and a pipette, the support frame is arranged above the processing device, the moving device is arranged on the support frame, and the pipetting device can be driven by the moving device to move on the support frame in order to realize sample extraction on the processing device and pipetting operation in the PCR reaction. The sample processing system integrates sample extraction, PCR reaction and pipetting assemblies, meets the existing requirements for automation and integration of an apparatus, is convenient to operate, can be used individually or together with a capillary electrophoresis device according to different target scenarios, has a wide application range.

Description

technical field [0001] The invention relates to the field of biochemical detection, in particular to an integrated sample processing system. Background technique [0002] Since the birth of the DNA double helix model of Watson and Crick, biology has entered a new era. In the field of biology, DNA must be said, and the central dogma must be discussed. basis for scientific research in all disciplines. The existing DNA extraction methods mainly include: column extraction method, salting out method, magnetic bead method, etc. [0003] Polymerase chain reaction (referred to as PCR reaction) is a molecular biology technique used to amplify specific DNA fragments. It can be regarded as special DNA replication outside the body. A substantial increase. Therefore, whether it is ancient organisms in fossils, the remains of historical figures, or the hair, skin or blood left by the murderer in a murder case decades ago, as long as a little DNA can be isolated, it can be amplified by ...
