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
