Resazurin Cell Viability Assay is a reliable, sensitive and easy-to-use fluorescent assay that detects cellular metabolic activity. Resazurin (7-Hydroxy3H-phenoxazin-3-one 10-oxide) is a blue dye non-fluorescent until it is irreversibly reduced to the pink colored and highly red fluorescent resorufin by dehydrogenase enzymes in metabolically active cells.

The fluorescent signal is monitored using 530-560 nm excitation wavelength and 590 nm emission wavelength. The absorbance is monitored at 570 nm and 600 nm. The fluorescent or colorimetric signal generated from the assay is proportional to the number of living cells in the sample.


  • Spectrophotometric quantification of cell proliferation and viability in response to pharmaceutical, chemical, nutrients and environmental compounds.

  • High Throughput Screening.


  • 4 x 25 mL Resazurin solution


  • Shipped in: Ambient Temperature.

  • Storage: It can be stored at 4 °C in the dark for up to 12 months and at –20 °C in the dark for long term storage.

  • Guaranteed: All components are stable for at least  10 freeze-thaw cycles.

  • Recommendations: Storage in the dark and  Thaw Resazurin solution completely and mix thoroughly before use.
