Methoden & Expertise zur Forschungsinfrastruktur
With the O2k-FluoRespirometer small amounts of biological samples can be used for bioenergetic and OXPHOS analysis, ranging from isolated mitochondria, permeabilized tissues and permeabilized cells to living cells and tissue slices. It is used to simultaneously measure and monitor oxygen consumption and either ROS production (AmR), mitochondrial (mt-) membrane potential (TMRM, Safranin and Rhodamine), Ca2+ (CaG) or ATP production (MgG). The O2k-FluoRespirometer supports all add-on MultiSensor Modules: O2k-TPP+ ISE-Module, O2k-pH ISE-Module, O2k-NO Amp-Module, enabling measurement of mt-membrane potential with ion sensitive electrodes (ISE for TPP+ or TPMP+ ) or pH.
The modular O2k-Concept is supported by the specially developed O2k-Software, DatLab 7, guiding the user step-by-step through the desired experiment. In addition, international O2k-Workshops are provided on a regular basis, allowing for hands-on practical training.
Oroboros Instruments boasts over 25 years of experience and offers the leading instrument on the market in mitochondrial physiology and pathology.
The O2k-Network includes and connects over 600 reference laboratories worldwide and labs, hospitals, research centers, pharmaceutical and biotech companies in 49 countries.
The open-access preprint server, MitoFit Preprint Archives, encourages the sharing of knowledge in the field and supports our strong belief in having an open source platform for customers and network.
