Step 2.4.12 of the Protocol was updated from:

Finally, inject 1 µL of 5 mM antimycin A (2.5 µM final concentration). This is a complex II inhibitor to discriminate between the mitochondrial and residual oxygen consumption (non-mitochondrial respiration). For the analysis of complex I, add 1 µL of 1 mM rotenone (0.5 µM final concentration), an inhibitor of this complex, instead of AA. Measure the oxygen consumption until the signal decreases and stabilizes.

Finally, inject 1 µL of 5 mM antimycin A (2.5 µM final concentration). This is a complex III inhibitor to discriminate between the mitochondrial and residual oxygen consumption (non-mitochondrial respiration). For the analysis of complex I, add 1 µL of 1 mM rotenone (0.5 µM final concentration), an inhibitor of this complex, instead of AA. Measure the oxygen consumption until the signal decreases and stabilizes.

Figure 3 in the Representative Results section was updated from:

Figure 3: Determination of the optimal concentration of digitonin for the permeabilization of human sperm cells. The respiration rates were measured at 37 °C in MRM medium with glutamate, malate, and adenosine diphosphate. (A) Representative respiratory trace. The blue line is the O₂ concentration, and the red line represents the O₂ flow per volume correlated. (B) Mitochondria respiration rate means ± standard error, n = 4. The red arrow represents the optimal concentration. Abbreviation: dig = digitonin. Please click here to view a larger version of this figure.
