  • 50 μl/well of cell suspension (20,000 cells/well)
  • Incubate 40-48 hours, add Redox Dye Mix

(tetrazolium) and incubate for 24 hours

  • Plate substrates:
  • 1. Carbon energy sources

(sugars, polysaccharides, nucleotides,and carboxylic acids) 2-4. Amino acids and dipeptides

  • 5. Ions

6-8. Hormones and metabolic effectors
