O2k-Core to FluoRespirometer

O2k-Modules

O2k-Modules are add-on modules supported by the O2k. When one (or more) analytical parameters are monitored simultaneously with oxygen concentration and oxygen flux in the O2k, this is an O2k-MultiSensor application. The O2k fully supports the O2k-Modules.

High-resolution respirometry is extended by O2k-MultiSensor modules allowing the simultaneous measurement of oxygen consumption and one additional parameter. 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:

  1. Quality control of preparations by respirometric performance.
  2. Objective exclusion criteria for protocol related problems, e.g. overtitration of uncouplers, side effects of TPP+ or fluorophores.
  3. Elimination of artifacts of normalization for a mitochondrial marker when combining two methods in a single chamber.
  4. Additional information is acquired for a limited amount of sample.
  5. Oxygen dependence of parameters can be studied.
