MICRO-TOTAL ANALYSIS CHIP, CHIP ASSEMBLY, AND METHOD FOR PREPARING SINGLE CELL SAMPLE

摘要

A micro-total analysis chip (20), a chip assembly (2), and a method for preparing a single cell sample. The micro-total analysis chip (20) is used for preparing the single cell sample, and comprises at least two inflow ports, one outflow port (14), and multiple flow channels connecting the inflow ports and the outflow port (14). The inflow ports are used for enabling a cell suspension, a molecular tag, and a cell isolation medium to enter the multiple flow channels; the outflow port (14) is used for enabling the single cell sample to flow out of the flow channel; the inflow ports are located on the upper surface of the chip (20), and the outflow port (14) is located on the lower surface of the chip (20). The single cell sample can flow out of the outflow port (14) depending on the effect of the gravity.
