Did you know that safranin can exert an inhibitory effect on mitochondrial respiration? Application of safranin leads to partial inhibition of NADH-linked respiration and above 2 µM on the succinate-linked respiration. By running a control high-resolution respirometry experiment without the fluorophore, you can detect and do quality control for this inhibitory effect. - You can read more about it in the following publication: »Krumschnabel 2014 Methods Enzymol«  - communicated by »Komlodi Timea« and »Cecatto Cristiane«

LEAK respiration relates to intrinsic uncoupling. Non-phosphorylating LEAK respiration is measured in the absence of externally added uncouplers (i) in the absence of adenylates, (ii) after depletion of ADP, or (iii) after inhibition of ATP synthase or adenine nucleotide translocase. - »BEC2020.1: Mitochondrial physiology« - Table 2. Terms on respiratory coupling and uncoupling - communicated by »Komlodi Timea« and »Cecatto Cristiane« and »Gnaiger Erich«
