CCK8/mtt/cell proliferation assay
Cell proliferation is the basis of organism growth, development, reproduction and heredity. For tumor research, cell proliferation is closely related to cell apoptosis, cell cycle and other phenotypes, and it is also one of the important contents of molecular biology and pharmacology research. MTT or CCK8 is a commonly used method to detect cell proliferation, which can be used to study the toxic effect of drugs on cells, or to explore the effect of overexpression or interference of a gene in cells on cell proliferation, so as to provide a basis for further study of gene function. The principle of MTT technology is that MTT (thiazole blue) can pass through the cell membrane and enter the cell. Dehydrogenase in the mitochondria of living cells can reduce exogenous MTT to blue-purple crystals insoluble in water and deposit them in the cell, while dead cells do not have this function. Crystals can be dissolved in DMSO, and their light absorption value can be measured at 490nm wavelength by enzyme-linked immunosorbent detector, this indirectly reflects the number of living cells (within a certain range, the higher the optical density value, the stronger the cell viability). The principle of CCK8 technology is that the WST-8 in the CCK-8 reagent can be reduced to a highly water-soluble yellow product by dehydrogenase in the mitochondria of living cells under the action of the electron carrier 1-methoxy-5-methylphenazinium dimethyl sulfate (1-MethoxyPMS). The light absorption value of the enzyme-linked immunosorbent assay at 450nm wavelength can indirectly reflect the number of living cells (within a certain range, the amount of yellow product generated is proportional to the number of living cells).
