A practical perspective on how to develop, implement, execute, and reproduce high-resolution respirometry...

Area of Science:

• Mitochondrial physiology and bioenergetics
• Analytical instrumentation in biological research

Background:

• High-resolution respirometry (HRR) is crucial for studying mitochondrial respiratory control.
• The Oroboros Oxygraph 2000 (O2k) is a widely used instrument for measuring mitochondrial respiration rates.
• Inherent data variability in HRR can hinder bioenergetics research progress.

Purpose of the Study:

• To advocate for best practices in planning and conducting O2k experiments.
• To enhance transparency and reproducibility of HRR data across laboratories.
• To provide guidance for both new and experienced O2k users.

Main Methods:

• This perspective focuses on guidance for O2k experimental design and execution.
• Key areas include mitochondrial preparation and protocol selection.
• Measures to increase the reproducibility of HRR data are discussed.

Main Results:

• The O2k platform offers significant potential for answering complex bioenergetic questions.
• Implementing standardized protocols and best practices is essential for reliable results.
• Addressing data variability is critical for advancing mitochondrial research.

Conclusions:

• Adherence to best practices will improve the reliability and validity of O2k data.
• This perspective aims to promote the effective use of the O2k instrument.
• Standardized methods will serve as a valuable reference for researchers and peer reviewers.
