| 摘要 |
In the invention, a fluid cell, used for sequencing reaction between DNA fragments and reagents, comprises: a reaction chamber, one inner side of which is fixed with multiple DNA fragments; a reagent inlet and a reagent outlet, which are separately located at each end of the other inner side of the reaction chamber and used for reagents flowing into and out from the reaction chamber. Multiple DNA fragments are fixed on the reaction chamber with the small capacity as short tag arrays in sequence and make the reaction go on at the condition of the reagents without diffusion barriers, which improves the contacts of reagents and DNA fragments so as to shorten the reaction time. At the same time, the demands to the concentration and dosage of reagents are low, which reduces the consumption of reagents. As the result, the sequencing cost cut down. Multiple DNA fragments are fixed on the fluid cell at the same time, which provides a way for parallel reaction of various fragments. The automatic high-through sequencing and fast sequencing reactions are achieved in the invention.
