The invention provides a sequencing reaction cabinet, used for carrying out the sequencing reaction between DNA fragments and a reagent; the sequencing reaction cabinet comprises a reaction cavity, on the inner wall at one side of which is fixedly provided with a plurality of DNA fragments; a reagent inlet and a reagent outlet which are respectively arranged at the two ends of the inner wall at the other side of the reaction cavity and are respectively used for the reagent to flow into and out of the reaction cavity. In the sequencing reaction cabinet, a plurality of DNA fragments are fixed in the reaction cavity with a small capacity as a short label array for sequencing to lead the sequencing reaction to be carried out in the reagent without a diffusion barrier, thus greatly improving the accessibility between the reagent and the DNA fragments and further shortening the reaction time; the requirements to the concentration and the dosage of the reagent is lower, thus consuming less reagent and reducing the sequencing cost. While a plurality of DNA fragments are simultaneously fixed in the reaction cabinet to provide a platform for realizing the parallel reaction of a plurality of fragments. The sequencing reaction cabinet used for carrying out sequencing reaction between DNA fragments and a reagent realizes the automatization of high pass sequencing and can realizes fast sequencing reaction.

Thermocycling system, including methods and apparatus, for performing a flow-based reaction on a sample in fluid. The system may include a plurality of segments defining at least two temperature regions, and also may include a plurality of heating elements configured to maintain each temperature region at a different desired temperature. At least one of the heating elements may be a thermoelectric cooler operatively disposed to transfer heat to and / or from a temperature region The system further may include a fluid channel extending along a helical path that passes through the temperature regions multiple times such that fluid flowing in the channel is heated and cooled cyclically.
