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]

The CellTiter-Blue® Cell Viability Assay uses an optimized reagent containing resazurin. The homogeneous procedure involves adding the reagent directly to cells in culture at a recommended ratio of 20µl of reagent to 100µl of culture medium. - [Read Cell Viability Assays that Measure Metabolic Capacity 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]

Assay measures cell viability. It is a two-color fluorescence assay that simultaneously determines Live cell number and Dead cell number. This protocol is designed for use with the GEMINI XS Microplate Spectrofluorometer, a multi-well plate scanner with dual excitation/emission capabilities, but the assay is also adaptable for flow cytometry and fluorescence microscopy. Includes: Cell Culture; Preparation for the Assay; Live/Dead Assay; Reading the Plate; Data Analysis; Alternative protocol. - [Read Live/Dead Assay for Cell Viability Protoco]

The MTT Cell Proliferation Assay measures the cell proliferation rate and conversely, when metabolic events lead to apoptosis or necrosis, the reduction in cell viability. The number of assay steps has been minimized as much as possible to expedite sample processing. The MTT Reagent yields low background absorbance values in the absence of cells. Includes: Determining optimal cell counts, performing an assay, data interpretations and troubleshooting. - [Read MTT Cell Proliferation 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]
