O2k-Demo, O2k-MultiSensor
- Β» The OROBOROS MitoLab uses Safranin O from Sigma (#S2255, 25 g).
- Β» More details: Β»DiscussionΒ«.
Safranin chemical background
Several substances typically used in SUIT protocols may influence the fluorescence signal from safranin when injected into the O2k-Chamber (for instance colored substances such as cytochrome c). The chemicals used should be tested for this 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
