Brief introduction: Most microchip experiments require multi-step sample preparation processes, such as DNA, RNA, or protein extraction multiplication, that can produce unpredictable human errors and variations when repeated. Instead, small molecules or gene arrays will be made on a chip, and cells will be applied to it. When cells are attached to each genetic material on the chip, each gene is slowly released and absorbed into the cell, as is the behavior of the vector animal. If a vector expresses a receptor on the surface of a cell, the receptor sequence will be constructed on the surface of the cell to screen for future tests. Not only DNA or proteins, but entire cells or organs can be arranged on the surface of the glass to produce a cell chip or tissue chip. For example, if you want to find ligands that are bonded to the cell membrane receptor, you need to lay out the whole cell instead of isolating the receptor and using the plate. If the matrix is made up of different cells, it will be easy to identify the cell-specific ligand. This method will be widely used. For example, if the ligand is bonded to a particular cancer cell, the control reagent or toxin replacement will be attached to the ligand, and each image will be analyzed and processed. Cell screening chip is a kind of cell chip, which is mainly used to screen cells, which is more convenient and fast to achieve the purpose of cell screening.
