Tumor Cell Proliferation Assay

Direct determination of DNA synthesis is one of the most accurate methods to detect tumor cell proliferation, and it is also a basic method to determine substance toxicity, drug safety evaluation and cell health. At present, the commonly used tumor cell proliferation detection methods include thymine nucleoside (3H-TdR) infiltration method, MTT detection, hydroxyfluorescein diacetate succinimide (CFSE) detection, and Brdu detection. We have high-quality researchers and experienced teams to provide you with personalized experimental solutions related to tumor cell proliferation. With the most accurate experimental results to help you better carry out cancer-related scientific research.

Cell Counting Kit, abbreviated as CCK-8, is a rapid and highly sensitive detection kit widely used in cell proliferation and cytotoxicity. In the presence of electron coupling reagents, WST-8 can be reduced by dehydrogenase in the mitochondria to a highly water-soluble yellow nail product. The depth of color is directly proportional to cell proliferation and inversely proportional to cytotoxicity. The OD value at the wavelength of 450nm was measured by enzyme labeling instrument, which indirectly reflected the number of living cells.

MTT method, also known as MTT colorimetric method, is a method to detect cell survival and growth. The detection principle is that succinate dehydrogenase in the mitochondria of living cells can reduce exogenous MTT to water-insoluble blue-purple crystal methylazan and deposit in the cells, while dead cells do not have this function. Dimethyl sulfoxide can dissolve methylazan in cells, and its light absorption value is measured at 540 or 720nm wavelength by enzyme-linked immunosorbent assay (Elisa), which can indirectly reflect the number of living cells. In a certain range of cell number, the amount of MTT crystallization is proportional to the number of cells.

Scope of application

MTT method has been widely used in the activity detection of some bioactive factors, large-scale screening of antineoplastic drugs, cytotoxicity test and tumor radiosensitivity test.

At present, CCK-8 has been widely used in high-throughput drug screening, cell proliferation test, cytotoxicity test, tumor drug sensitivity test and biological factor activity test and so on.
