Which electron microscope techniques can be used to study which aspects of cell membrane?

Cell culture Cell culture technology is also called cell cloning technology, and the formal term in biology is cell culture technology. Cell culture is an indispensable process for the whole bioengineering technology or one of the biological cloning technologies, and cell culture itself is a large-scale cloning of cells. Cell culture technology can transform a cell into a simple single cell or multi-cell with little differentiation after a large number of cultures, which is an essential link of cloning technology, and cell culture itself is cell cloning. A large number of cells or their metabolites are obtained by cell culture. Because biological products are all derived from cells, it can be said that cell culture technology is the most core and basic technology in biotechnology.

Research and application of cell culture technology

1. directly observe the morphological structure and life activities of living cells. Used in cytology, genetics, immunology, experimental medicine and oncology. 2. It is convenient to take photos by directly observing the changes of cells. 3. Study cell types, such as from low to high to human, from embryo to adult, from normal tissue to tumor. 4. Using various techniques, such as phase contrast, fluorescence, electron microscope, histochemistry and isotope labeling, we can observe and study the cell state conveniently. 5. It is not only the research object of molecular biology and genetic engineering, but also its main component. 6. It is easy to apply physical, chemical and biological experiments. 7. It is easy to provide a large number of experimental objects with similar biological characteristics, and the cost is low. 8. Become a raw material source for monoclonal antibody production and genetic engineering of biological products. Cells attached to the surface of the support grow, and cells that can only grow through attachment are called anchor-dependent cells, which are related to cell differentiation.
