Abstract: High-resolution respirometry [1] is extended by MultiSensor techniques allowing the simultaneous measurement of oxygen consumption and one additional parameter (mitochondrial membrane potential, pH, Ca2+, or NO concentration [2, 3]). Fluorometric methods are available for a wide range of analytical parameters of major interest in mitochochondrial physiology: H2O2 production, mitochondrial membrane potential, intracellular pH, Ca2+, Mg2+ , and NADH levels. Advantages of the simultaneous measurement of additional parameters in a single respirometric chamber:
- Quality control of preparations by respirometric performance.
- Objective exclusion criteria for protocol related problems, e.g. overtitration of uncouplers, side effects of TPP+ or fluorophores.
- Elimination of artifacts of normalization for a mitochondrial marker when combining two methods in a single chamber.
- Additional information is acquired for a limited amount of sample.
- Oxygen dependence of parameters can be studied.
Here we introduce the O2k-Fluorescence LED2-Module, describe one selected stage in its development, and show its application for the simultaneous measurement of respiration and H2O2 production of mouse brain mitochondria. • Keywords: Oxygraph-2k, High-resolution respirometry, Spectrofluorometry, MitoCom
