  • In vitro assay platform using human ES-derived hNP1 Neural Progenitor Cells or hN2 Neuonal cells for in vitro neurotoxicity testing.
  • Incorporates the most sensitive ATP bioluminescence readout available to measure proliferation, cytotoxicity, cell number and even apoptosis.
  • NeuroGlo™-Tox HT is a calibrated and fully standardized assay platform allowing results to be compared over time.
  • NeuroGlo™-Tox HT incorporates specific neural growth media.
  • High-throughput capability using 96- or 384-well plate formats allows ADME-Tox drug or compound screening, thereby significantly reducing unexpected results during pre-clinical testing.
  • 2D and 3D stem cell culture and high throughput toxicity testing capability.
  • Results usually within 7 days.
  • Validated readout according to FDA Bioanalytical Method Guidelines.
  • Designed for multiplexing with other assay using the same sample (see below).
  • A 3Rs Assay Platform-Helps Reduction, Refinement, Replacement for animal testing.
