The CellTiter-Glo® Luminescent Cell Viability Assay(a) is a homogeneous method to determine the number of viable cells in culture based on quantitation of the ATP present, which signals the presence of metabolically active cells.
The CellTiter-Glo® Luminescent Cell Viability Assay is a homogeneous method of determining the number of viable cells in culture based on quantitation of the ATP present, an indicator of metabolically active cells.
MTT assays are frequently used to assess 3D microtissue cultures using Matrigel® substrate.
However, due to its enhanced lytic capacity, the CellTiter-Glo® 3D Assay is better able to penetrate 3D microtissues.
