CellTiter-Glo One Solution Assay, 500ml

The CellTiter-Glo One Solution Assay is a homogeneous method of determining the number of viable cells in culture based on quantitation of the ATP present, which indicates the presence of metabolically active cells. The frozen, ready-to-use format is based on the original CellTiter-Glo Luminescence Cell Viability Assay chemistry and eliminates the need to combine buffer with lyophilized substrate when preparing reagent. The CellTiter-Glo Assay is designed for use with multiwell-plate formats, making it ideal for automated high-throughput screening (HTS) in 96- to 1536-well format, and cell proliferation and cytotoxicity assays. The homogeneous "add-mix-measure" format results in cell lysis and generation of a luminescent signal proportional to the amount of ATP present. The amount of ATP is directly proportional to the number of cells present in culture. The CellTiter-Glo One Solution Assay generates a stable "glow-type" luminescent signal with a half-life of greater than three hours. This extended half-life eliminates the need for reagent injectors and provides flexibility for continuous or batch-mode processing of multiple plates.
