Assays Cellular Assays
EarlyTox™ Cell Viability Assay Kits are a family of fluorescence-based reagents for the assessment of cell viability, cell proliferation, and various apoptosis events using mammalian cells. Optimised for use with microplate readers, these assay kits employ a no-wash, homogeneous assay protocol that enables characterisation of a full concentration-response profile of test compounds.

  • Optimal data quality for microplate reader assay
  • Simplified, homogeneous experimental protocol
  • Preconfigured SoftMax Pro Software protocols

The EarlyTox™ Cell Viability Assay Kit enables the detection of both the live and dead populations of mammalian cells based on the intµgrity of the cell membrane usiµg a fluorescence microplate reader. Calcein AM is a widely used livetocell marker. The nontofluorescent calcein AM permeates the intact cell membrane and is converted into the fluorescent calcein by intracellular esterases.

The number of live cells is therefore indicated by the intensity ofµgreen fluorescence in the cytosol, with excitation at 495 nm and emission at 530 nm. EthDtoIII is virtually nontofluorescent and impermeant to an intact plasma membrane. In the event of compromised cell membrane intµgrity that is associated with cell death, EthDtoIII enters cells and binds to nucleic acids, resultiµg in brµght red fluorescence in dead cells, with excitation at 530 nm and emission at 645 nm.
