  Cytotoxicity 2 Multiparameter Kit


The Cytotoxicity 2 (multiparameter) HCS Reagent Kit contains optimized reagents for simultaneous detection and quantitation in the same cell of changes in nuclear morphology and size, the cell membrane’s permeability status, changes in cell density (number of cells per field) from compound toxicity, and changes induced to EITHER the lysosome’s mass or pH OR the mitochondria’s transmembrane potential.  For these indicators of cell health, the supplied fluorescent reagents enable a fixed end-point assay in cells grown on standard high-density microplates.

   Product Detail


Cytotoxicity 2 Multiparameter Kit Features
  • Available in multiplex or singleplex configurations
  • Optimized protocol requiring no cell lysis, purification or filtration steps
  • Immunofluorescence-based assay provides sensitive results without radioactivity
  • Cells prepared with the HCS Reagent Kit may be analyzed directly via standard fluorescence microscopy; or HCS imaging systems
  • Assay is versatile and widely applicable to a variety of cell types

Three kit versions are available in two sizes. One version contains fluorescent probes for nuclear morphology/size (blue fluorescence), cell membrane’s permeability status (green fluorescence), lysosome mass or pH (orange fluorescence), and mitochondrial transmembrane potential (orange fluorescence). Because the probes for lysosomal mass and mitochondrial potential have similar spectra, this kit can be used to measure either organelle’s properties, depending on which fluorescent probe is used. The other two versions have, in addition to the nuclear and cell permeability probes, either the lysosomal or the mitochondrial fluorescent probe.

These reagents have been optimized for use with the ArrayScan® HCS Reader and the Cell Health Profiling BioApplication. These kits can also be used with other Cellomics BioApplication Modules. Thus, automated plate handling, focusing, image acquisition and processing, and data analysis and management are combined in one high content screening (HCS) system to assay for compound toxicity. The kit also can be used as a cell health assay to quantify the number and percentage of cells in the population beyond the normal range. Additionally, compounds can be identified that affect cell population density. Cells labeled by reagents in this kit also can be viewed and analyzed by other fluorescence microscopy-based instruments.
