The working principle is based on dehydrogenase activity detection. The generated NADH from the reaction of dehydrogenase enzymes and the substrates oxidizes the 1-methoxyPM. The reduced 1-methoxyPMS further oxidizes the tetrazolium salt (WST-8) in the CCK-8 assay kit, forming the yellow formazan dye. The dye color can then be quantified by measuring the absorbance at 460 nm wavelength so that the cell number is known. The assay can be used for the measurement of cell proliferation in response to growth factors, cytokines, mitogens, nutrients, etc. It can also be used for the analysis of cytotoxic compounds like anticancer drugs and many other toxic agents and pharmaceutical compounds.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003e\u003cimg class=\"alignnone wp-image-9093 size-full lazyloaded\" src=\"https:\/\/tribioscience.com\/wp-content\/uploads\/2021\/05\/TBS2022-6.png\" alt=\"\" width=\"1747\" height=\"708\" data-lazy-sizes=\"auto, (max-width: 1747px) 100vw, 1747px\" data-was-processed=\"true\"\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003ePrinciple\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003e\u003cimg class=\"alignnone wp-image-7579 \" src=\"https:\/\/tribioscience.com\/wp-content\/uploads\/2021\/05\/CCK-8-3.png\" alt=\"\" width=\"559\" height=\"216\"\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSimplicity: One-bottle, ready-to-use solution.
