Abstract: High-resolution respirometry with mitochondria, cells or biopsies is based on the unique features of the OROBOROS O2k, combining instrumental design, electronics and task-specific DatLab software. Various respiratory states are analyzed with <0.4 million cells or <4 mg biopsy (muscle, liver) per assay. Complex substrate/inhibitor titration protocols are used to quantify functional properties of selected components of the respiratory chain. The electronic titration-injection micropump TIP2k is applied for kinetics as a modular component of the O2k. DatLab provides on-line instrumental background corrections of oxygen flux and on-line data analysis, and tabulated results are available at the end of an experiment. This sets a new standard for biomedical and clinical studies, combining high-resolution with instant diagnostic information.
