Cell sorting is a laboratory technique used to separate different types of cells from a mixed population. This process is essential for studying specific cell types, understanding their functions, and conducting experiments in fields like immunology and cancer research. Various methods, such as flow cytometry and magnetic-activated cell sorting (MACS), allow researchers to isolate cells based on specific characteristics, such as size, shape, or surface markers. The sorted cells can then be analyzed or used for further experiments, such as gene expression studies or drug testing. By obtaining pure populations of cells, scientists can gain insights into cellular behavior and interactions, ultimately advancing our knowledge in biology and medicine.
