Cell Viability Assay - Information

Cell Viability Assay Kit (Colorimetric/Fluorometric) reagent has been optimized for maximum sensitivity, reproducibility and long shelf-life. The homogeneous cell-based assay can be performed in multi-well plates. The reagent is compatible with all culture media and with all liquid handling systems for high-throughput screening applications in 96-well and 384-well plates. Applications include cell proliferation, cytotoxicity and apoptosis.


Homogeneous assay for cell viability, proliferation, cytotoxcity and high-throughput screen for anticancer agents.

Cell Viability Assay - Key Features

  • Safe. Non-radioactive assay (cf. 3H-thymidine incorporation assay).
  • Sensitive and accurate. As low as 100 cells can be accurately quantified.
  • Time efficient. High-throughput assay in 96-well and 384-well plates allows simultaneous processing ten of thousands of samples per day.
  • Homogeneous and convenient. A single reagent and "mix-incubate-measure" type assay. No wash and reagent transfer steps are involved.
  • Robust and amenable to HTS. Z' factors of 0.6 to 0.9 are routinely observed in 96-well and 384-well plates. Can be readily automated on HTS liquid handling systems.

More Details

This homogeneous assay involves simply adding a single reagent, the colorimetric/fluorometric Cell Viability Assay Kit reagent, to the cell culture and measuring the fluorescence intensity (excitation wavelength = 530 - 570 nm, emission wavelength = 590 - 620 nm) after an incubation step.
