About NextGen-O2k

Oroboros - as a driving force in mitochondrial physiology - extends the analytical and diagnostic power of high-resolution respirometry by integration of NADH- and Q-redox monitoring in the NextGen-O2k. We aim at establishing the Oroboros quality control management for dissemination to our worldwide O2k-Network laboratories. This will become an effective contribution to address the acute reproducibility crisis of scientific investigation. In the spirit of Open Science and global networking, we will enable data sharing across projects and institutions in an Open Access database on mitochondrial physiology and pathology, to resolve the inflation crisis and ultimately the value-impact crisis of present academic publication. This will support key developments in mitochondrial medicine. In addition, we expand our business to algal biotechnology and ecology with the photobiology module of the NextGen-O2k, widening our focus from medicine to environment and climate.

Aims

Form the O2k to the NextGen-O2k

Between 1992 and 1994, Oroboros Instruments released its core technology for high-resolution respirometry (HRR), the Oxygraph-2k or O2k, for real-time monitoring of oxygen consumption of mitochondria, tissues, and living cells. Dissolved oxygen is measured using high-resolution polarographic oxygen sensors. Its main advantages are the unique signal stability and resolution of oxygen. HRR is the core technology present in every single of the devices and it will remain the basis of the NextGen-O2k.

In 2012, the updated version of the O2k was launched, the O2k-FluoRespirometer. The integrated Smart Fluo-Sensors combine fluorescence excitation and detection of defined wavelengths that in combination with fluorophores allow for the measurement of additional mitochondrial parameters, such as membrane potential, H₂O₂ production, calcium concentration, and ATP production.

The unique software DatLab has been developed for data acquisition and analysis. DatLab allows the researcher to perform calibrations (including automatic barometric and temperature adjustments), background correction, experimental SUIT (substrate-uncoupler-inhibitor-titration) protocols and data analysis.

With the O2k core technology, developed exclusively by Oroboros for high-resolution measurement of oxygen flux, the NextGen-O2k was developed.

Term	Abbreviation	Description
Hydrogen peroxide	H₂O₂	Hydrogen peroxide, H₂O₂ or dihydrogen dioxide, is one of several reactive oxygen intermediates generally referred to as reactive oxygen species (ROS). It is formed in various enzyme-catalyzed reactions (e.g., superoxide dismutase) with the potential to damage cellular molecules and structures. H₂O₂ is dismutated by catalase to water and oxygen. H₂O₂ is produced as a signaling molecule in aerobic metabolism and passes membranes more easily compared to other ROS.
Mitochondrial membrane potential	mtMP, Δψ [V]	The mitochondrial membrane potential, mtMP, is the electric part of the protonmotive force, Δp_H+. Δψ = Δp_H+ - Δµ_H+ / F mtMP or Δψ is the potential difference across the inner mitochondrial (mt) membrane, expressed in the electric unit of volt [V]. Electric force of the mitochondrial membrane potential is the electric energy change per ‘motive’ electron or per electron moved across the transmembrane potential difference, with the number of ‘motive’ electrons expressed in the unit coulomb [C].

NextGen-O2k Technical developments
Oxygen kinetics		Oxygen kinetics describes the dependence of respiration of isolated mitochondria or cells on oxygen partial pressure. Frequently, a strictly hyperbolic kinetics is observed, with two parameters, the oxygen pressure at half-maximum flux, p₅₀, and maximum flux, Jmax. The p₅₀ is in the range of 0.2 to 0.8 kPa for cytochrome c oxidase, isolated mitochondria and small cells, strongly dependent on J_max and coupling state.
PB-Module	PB-Module	The PB-Module has been developed for conducting measurements of PhotoBiology, including photosynthesis. It consists of the PB-Sensor and electronic components which are an integral part of the NextGen-O2k. Measurements are recorded and evaluated with the DatLab 8 software.
PB-Sensor		The PB-Sensor has been designed as a part of the PB-Module to provide with an external source of light, in the range of the blue (451 nm) or red (634 nm) wavelengths. This enables experiments for evaluating the production/consumption of O₂ in the presence of light. The PB-Sensor consists on one LED and one photodiode mounted on the sensor tip behind a plastic cover. The LED emits with blue or red light on the sample and its intensity can be regulated from 0 to 5000 µEinsteinsm^-2s^-1. The photodiode provides real-time measurement of the light intensity allowing for continuous adjustment to the desired value, which can also help compensate for the temperature rise due to the operation of the LED.
Q-Module	Q-Module	The Q-Module, developed both for measuring the Q redox state and for cyclic voltammetry measurements, is an integral part of the NextGen-O2k and consists of the Q-Sensor, integrated electronic components in the O2k, and the DatLab software.
Q-Sensor		The Q-Sensor has been designed as a part of the Q-Module for measurements with cyclic voltammetry and voltammetry, allowing for analysis of the Q redox state. The Q-Stopper with the reference electrode is called Q-Sensor, which is plugged in the NextGen-O2k. A three-electrode system is used to detect the Q redox state. Two of the three electrodes (glassy carbon and platinum electrode) are built into the Q-Stopper, while the reference electrode is removable (Reference-Electrode\2.4 mm).
