Good things come from out of the Blue.
The cell growth and cytotoxicity indicator dye that makes MTT obsolete. Use alamarBlue® instead of MTT, XTT, 3H Thymidine or neutral red.


The Science Behind TREK Lab Services
alamarBlue is an indicator dye, formulated to quantitatively measure the proliferation of a variety of human or animal cells, bacteria, mycobacteria, or fungi. It consists of an oxidation-reduction (REDOX) indicator that yields a colorimetric change and a fluorescent signal in a response to a metabolic activity.


  • Cell growth determinations
  • In vitro cytotoxicity
  • Cytokine assays

Enhanced Laboratory Efficiency

  • Water soluble – no extraction step required
  • Nontoxic to cells – no metabolic interference
  • Nontoxic to user – noncarcinogenic
  • Stable in culture – allows continuous monitoring of cells
  • Cytokine assay applications
  • Cell proliferations assay applications
  • Applicable for cell suspensions or attached cells
  • Proliferation data may be collected by either:
    • Fluorescence with excitation at 530-560 nm and emission at 590
    • Absorbance is monitored at wavelengths of 570 nm and 600 nm
  • Flexible – use any spectrophotometer or fluorometer
  • Nontoxic to the environment – no organic waste disposal problems
