Cytotoxicity positive control
WebCell cytotoxicity and proliferation assays are generally used for drug screening to detect whether the test molecules have effects on cell proliferation or display direct cytotoxic effects. Regardless of the type of cell-based assay being used, it is important to know how many viable cells are remaining at the end of the experiment. WebATP can be used to measure cell viability since only viable cells can synthesize ATP. ATP can be measured using the CellTiter-Glo ® Luminescent Cell Viability Assay (Cat.#. G7570) with reagents containing detergent, stabilized luciferase and luciferin substrate. The detergent lyses viable cells, releasing ATP into the medium.
