Safranin chemical background

Several substances typically used in SUIT protocols may influence the fluorescence signal of safranin when injected into the O2k-Chamber (for instance coloured substances such as cytochrome c). These chemicals should be tested for their effect in a background run without biological sample, and the necessary corrections be applied.

Substances with an effect on the fluorescence signal of safranin

  • ADP (D)
  • Cytochrome c (c)
  • Succinate (S)
  • Rotenone (Rot)
  • Ascorbate (As)
  • TMPD (Tm)

Substances without an effect on the fluorescence signal of safranin

* Pyruvate (P)
  • Malate (M)
  • Glutamate (G)
  • Digitonin (Dig)
  • Oligomycin (Omy)
  • FCCP (U)
  • Malonic acid (Mna)
  • Antimycin A (Ama)
  • DMSO
  • Ethanol
  • H2O2
  • H2O
