Problems solved by technology

Since the liquid pipetting workstation is an open platform, during the whole multi-step test operation, the operator needs to seal and open the 96-well plate film, or open and close a large number of tube caps from time to time, although part of the work is done by the workstation. Completed, but the overall still requires a lot of manual intervention, and it is impossible to realiz

Embodiment 1

[0039] Such as figure 1The nucleic acid detection pre-processing automation device shown is composed of a moving rail platform 1 , a base 2 , a movable magnet 3 , a pipette pump 4 and a pipette tip 5 . The pipette tip 5 is arranged on the pipette pump 4, and the pipette pump can move along the moving rail platform 1 and rotate through the rotating module. The mobile rail platform 1 moves and rotates on the upper part of the reagent plate through the pipette pump and the pipette tip to realize pipetting. The base 2 has a temperature control module corresponding to the position of the reagent disc. The base 2 is attached to the reagent tray to provide temperature control. The reagent disc can be rotated and moved by the rotating module on the base 2 .

[0040] Such as Figure 2-3 The reagent tray shown includes a cover plate 6 and a reagent tray 7. The reagent tray 7 is provided with a number of reagent holes 8, the reagent holes 8 are filled with pretreatment reagents for n...

Embodiment 2

[0043] Plasma free DNA is small fragments, fragmented DNA, the fragment length is between 100-300bp, and the peak value is around 160bp. In 1997, Professor Lu Yuming discovered that the peripheral plasma of pregnant women contained fetal cell-free DNA, and thus pioneered the use of cell-free DNA as the source of detection to analyze whether the fetus of a pregnant woman has chromosomal abnormalities. Circulating tumor DNA (ctDNA) derived from tumor cells also exists in plasma. ctDNA is widely used for tumor liquid biopsy, which can be used for non-invasive early diagnosis, companion diagnosis, and prognosis follow-up.

[0044] The conventional detection method is to first extract DNA from clinical samples, including plasma, to perform nucleic acid detection, processing, and detection in three steps. It takes 6 to 13 hours to complete the entire sample test. Among them, the extraction of sample nucleic acid and the pre-treatment process of detection are cumbersome.

[0062] The research object of transcriptome sequencing is the sum of all RNAs that can be transcribed by a specific cell in a certain functional state, mainly including mRNA and non-coding RNA. Transcriptome research is the foundation and starting point of gene function and structure research. Through next-generation high-throughput sequencing, it is possible to comprehensively and quickly obtain almost all transcript sequence information of a specific tissue or organ in a certain state, which has been widely used In basic research, clinical diagnosis and drug development and other fields.

[0063] The conventional detection method is to first extract RNA from clinical samples including whole blood and plasma, and then perform nucleic acid detection processing and detection in three steps. It takes 6 to 30 hours to complete the entire sample test. Among them, the extraction of sample nucleic acid and the pre-treatment process of detection are cumbersome.
