Cell Culture Media Supplements & Reagents


Resazurin can be utilized as a simple and quantitative method for measuring cell proliferation, viability, and cytotoxicity. It is a non-toxic, water soluble, redox-sensitive dye that changes from its blue/non-fluorescent state to a pink/highly-fluorescent state upon reduction by viable cells. Fluorescence can be read using 544 nm excitation and 590 nm emission wavelengths or absorbance can be read using a spectrophotometer set at 570 nm.

  • Label: Resazurin changes from blue/non-fluorescent to pink/highly-fluorescent
  • Testing Format: Microplate reader
