O2k-Catalogue

Description Oroboros O2k - the modular system for high-resolution respirometry and fluorometry for mitochondria and cell research, using small amounts of biological samples. The O2k-Fluorometer is the basis for combined measurement of respiration and fluorometric signals, supported by the Titration-Injection microPump and DatLab 7 (new). The modular O2k-concept yields a high flexibility of fluorespirometry with add-on O2k-MultiSensor Modules for research in mitochondrial physiology and pathology.

Oroboros O2k: development and distribution

  • O2k-Fluorometry: HRR combined with measurement of ROS production, mitochondrial membrane potential, ATP production, Ca2+, pH.
  • Titration-Injection microPump TIP2k: The O2k-TIP2k combination allows operation with programmable titration regimes, feedback control, and at steady-states, yielding a new flexibility in experimental design by combining the technical advantages of closed and open systems approaches. Automatic titrations for kinetics; feedback-controlled instrumental background tests; respiration in a closed or open system, in aerobic-anaerobic transitions or at steady-state oxygen concentrations, covering the entire physiological oxygen range and the extremes of hypoxia.
  • O2k-Modules can be combined in any configuration with the O2k-Fluorometer, and can be added any time to extend the O2k according to application-specific objectives: potentiometry (pH, TPP+ or TPMP+ for mitochondrial membrane potential, Ca2+) and amperometry (NO, H2S).

An Integrated Systems Approach: High-resolution fluorespirometry

O2k-Core basic.jpg
The Oroboros O2k is the unique state-of-the-art instrument for HRFR - where high-resolution counts:
  • with small amounts of cells or tissue,
  • at low respiratory activities,
  • multiple substrate-uncoupler-inhibitor titrations (SUIT protocols) with resolution of changes in oxygen flux over prolonged incubation times,
  • flexibility of O2k-MultiSensor applications,
  • fast transitions at low oxygen levels,
  • stability and quality control.
High-resolution respirometry is the result of our long-term expertise in instrumental design, software development, mitochondrial physiology, clinical and pharmacological applications, and world-wide scientific cooperation. The innovative O2k-developments provide a system of highest quality and distinguish high-resolution respirometry as a method and concept.
Today, such high resolution meets rapidly increasing demands, reflected by the increasing number and high level of O2k-Publications. Applications of the O2k in leading O2k-Network Labs are the driving forces for a rapid advancement of mitochondrial physiology. Open access to the O2k-Manual is an integral part of the concept of OROBOROS INSTRUMENTS on Gentle Science and Scientific Social Responsibility. With sharing of O2k-Protocols and implementation of quality control, the study of mitochondrial and cell respiration emerges as a quantitative science. Thus high-resolution fluorespirometry provides the foundation for comparative mitochondrial physiology, biomedical research, translation into clinical applications, establishing quantitative functional mitochondrial diagnosis.
The Oroboros O2k sets a world-wide standard in high-resolution respirometry - for mitochondrial studies in cell physiology and pathology. Developments progress beyond oxygen.
In contrast to merely offering an oxygen measuring device, the Oroboros O2k is integrated into a systems approach to high-resolution respirometry. This spans from experimental tools which are invaluable in the lab (e.g. ISS), or little aids that are crucial for tissue preparation (forceps), mitochondrial respration medium (MiR05-Kit), substrate-uncoupler-inhibitor titration protocols, and the unique O2k-Workshops.
