The CellTiter-Glo® Luminescent Cell Viability Assay is a homogeneous method to determine the number of viable cells in culture. Detection is based on using the luciferase reaction to measure the amount of ATP from viable cells. The amount of ATP in cells correlates with cell viability. - [Read Cell Viability Assays that Measure ATP Protocol]
Cell-based assays are important tools for contemporary biology and drug discovery because of their predictive potential for in vivo applications.This assay gives ratiometric, inversely proportional values of viability and cytotoxicity (Figure 4.15) that are useful for normalizing data to cell number. Also, this reagent is compatible with additional fluorescent and luminescent chemistries. - [Read Determining Number of Live and Dead Cells in Cell Population: Cytotoxicity Assay Protocol]
The latest generation of Promega cell-based assays includes luminescent and fluorescent chemistries to measure markers of cell viability, cytotoxicity and apoptosis, as well as to perform reporter analysis. Using these tools researchers can investigate how cells respond to growth factors, cytokines, hormones, mitogens, radiation, effectors, compound libraries and other signaling molecules. The protocols provided are guidelines for multiplexing cell-based assays & are intended as starting points. - [Read Multiplexing Cell Viability Assays Protocols]
