O2k FAQ
APPLICATIONS AND SAMPLES
The most common applications for the O2k are the following:
- Diagnosis of acquired and genetic mitochondrial diseases
- Diagnosis of myopathies and neuromuscular pathologies
- Studies on cell function and cell death - apoptosis and necrosis
- Measurement of oxidative stress
- Studies on ischemia-reperfusion injury
- Studies on aging and senescence
- Pharmacological tests

The O2k is a sole source apparatus, with no other available instrument meeting its specifications for high-resolution respirometry.
O2k high-resolution respirometry (HRR) is based on the O2k, combining chamber design, application of oxygen-tight materials, electrochemical and optical sensors, Peltier-temperature control and software features (DatLab) to obtain the unique sensitive and quantitative resolution of oxygen concentration and oxygen flux, with a closed-chamber or open-chamber mode of operation.
The O2k is a robust instrument, ready to be used for standard applications, providing high reliability, stability of the oxygen sensor over several months, and full software support. See: DatLab
The O2k can be routinely applied for cultured cells, intact cells and tissue biopsies, permeabilized cells and tissue biopsies, microbial cultures, oxygen-consuming enzymes, antioxidant systems, and, of course, isolated mitochondria. See: Respirometry and O2k-Publications
Compared to other instruments, the O2k requires five to ten times lower cell numbers for routine measurements of cell respiration, making it highly cost-, personell- and time-efficient.
When permeabilized biopsy preparations are utilized, the O2k provides the unique potential to reduce sample size to as little as 1 mg fresh weight per experimental run, supporting application of complex titration protocols.
The O2k is a 'chamber' approach, for application with tissue biopsies, cultured cells or isolated mitochondria. Whereas HRR cannot be applied for measurement of tissue O2 concentration, it is the method of choice for analysis of tissue O2 consumption and functional diagnosis of mitochondrial injuries.
Attached cells may be grown on disks before being introduced into the cylindrical chamber of the O2k. Alternatively, cells attached to beads can be used. With this method, however, gentle stirring, with the use of specific small stirring bars, is advisable to avoid crashing of the beads. Routinely, we apply the O2k on adherent cells after transfering them into suspension. For small cells, such as fibroblasts, 200,000 cells per chamber are required.
The O2k is designed to measure respiration plus one additional parameter at a time.
SOFTWARE COMPATIBILITY
No. As of now DatLab software is designed for Windows operating systems only.
