Amplex UltraRedAmplex® UltraRed (AmR) is used as an extrinsic fluorophore for measurement of hydrogen peroxide production (ROS) by cells or mitochondrial preparations. The reaction of H2O2 and AmR is catalyzed by horseradish peroxidase to produce the red fluorescent compound resorufin (excitation wavelength 563 nm, emission 587 nm; the fluorescent product according to the supplier is called UltroxRed in the case of Amplex® UltraRed which has a very similar structure to resorufin). The change of emitted fluorescence intensity is directly proportional to the concentration of H2O2 added, whereby the H2O2 is consumed.
Attached cellsMany cell types are grown in culture as attached cells, such as endothelial or neuronal cells in a monolayer.

CalciumCa2+ is a major signaling molecule in both prokaryotes and eukaryotes. Its cytoplasmic concentration is tightly regulated by transporters in the plasma membrane and in the membranes of various organelles. For this purpose, it is either extruded from the cell through exchangers and pumps or stored in organelles such as the endoplasmic reticulum and the mitochondria. Changes in the concentration of the cation regulate numerous enzymes including many involved in ATP utilizing and in ATP generating pathways and thus ultimately control metabolic activity of mitochondria and of the entire cell. Measuring changes in Ca2+ levels is thus of considerable interest in the context of high-resolution respirometry.
Calcium GreenCalcium Green denotes a family of extrinsic fluorophores applied for measurement of Ca2+ concentration.

ChlororespirationIn chlororespiration oxygen is consumed by a putative respiratory electron transfer system (ETS) within the thylakoid membrane of the chloroplasts and ATP is produced. It is a process that involves the interaction with the photosynthetic ETS in which NAD(P)H dehydrogenase transfers electrons to oxygen with the assistance of the photosynthetic plastoquinone (PQ), which acts as a non-photochemical redox carrier. Initially described in the unicellular alga Chlamydomonas reindhartdii, chlororespiration was highly disputed for years until the discovery of a NAD(P)H-dehydrogenase (NDH) complex (plastidic encoded) and plastid terminal oxidase (PTOX) (nuclear encoded) in higher-plant chloroplasts. PTOX is homologous to the plant mitochondrial alternative oxidase and has the role of preventing the over-reduction of the PQ pool while the NDH complexes provide a gateway for the electrons to form the ETS and consume oxygen. As a result of this process there is a cyclic electron flow around Photosystem I (PSI) that is activated under stress conditions acting as a photoprotection mechanism and could be involved in protecting against oxidative stress.

Cyclic voltammetryCyclic voltammetry (CV) is a type of electrochemical measurement which is applied with the Q-Module as quality control to

(1) determine the oxidation and reduction peak potentials of Coenzyme Q in the specific experimental condition, (2) check the quality of the Q-Sensor, and (3) test the interference of chemicals used in the HRR assay with the Q-Sensor. In CV, the Q-Sensor with the three-electrode system is used to obtain information about the analyte (CoQ) by measuring the current (I) as the electric potential (V) between two of the electrodes is varied. In CV the electric potential between the glassy carbon (GC) and the Ag/AgCl reference electrode changes linearly versus time in cyclical phases, while the current is detected between GC and platinum electrode (Pt). The detected current is plotted versus the applied voltage to obtain the typical cyclic voltammogram trace (Figure 1). The presence of substances that are oxidized/reduced will result in current between GC and Pt, which can be seen as characteristic peaks in the voltammogram at a defined potential. The oxidation or the reduction peak potential values are used to set the GC (integrated into the Q-Sensor) for a separate experiment to measure the Q redox state of a biological sample. The oxidation and reduction peak potentials can be influenced by 1) the respiration medium, 2) the type of CoQ, 3) the polarization window, 4) the scan speed, 5) the number of cycles, 6) the concentration of the analyte (CoQ), and 7) the initial polarization voltage. <be>

Enable DL-Protocol editingEnable DL-Protocol editing is a novel function of DatLab 7.4 offering a new feature in DL-Protocols: flexibility. Fixed sequences of events and marks can be changed (Skip/Added) in a SUIT protocol by the user. Moreover, the text, instructions, concentrations and titration volumes of injections in a specific DL-Protocol can be edited and saved as user-specific DL-Protocol [File]\Export\DL-Protocol User (*.DLPU). To enable it, under the 'Protocols' tab in the menu, select the option 'Enable DL-Protocol editing', and then select the plot in which the marks will be set (e.g., O2 flux per V). Select the 'Overview' window, where you will be able to edit events and marks names, definition/state, final concentration and titration volumes, as well as select a mark as 'multi' for multiple titration steps, skip a mark, or add a new event or mark. After saving, export a DL-Protocol User (DLPU) and load it before running the next experiments. If users of DatLab versions older than DatLab 7.4 wish to alter the nature of the chemicals used or the sequence of injections, we ask them to contact the O2k-Technical Support.

Fatty acid oxidationFatty acid oxidation (β-oxidation) is a multi-step process by which fatty acids are broken down to generate acetyl-CoA, NADH and FADH2 for further energy transformation in the mitochondrial matrix. Whereas NADH is the substrate of CI, FADH2 is the substrate of Electron-transferring flavoprotein complex (CETF) which is localized on the matrix face of the mtIM, and supplies electrons from FADH2 to CoQ2. Before the mitochondrial transport for ß-oxidation, fatty acids (short-chain with 1-6, medium-chain with 7–12, long-chain with >12 carbon atoms) are activated by fatty acyl-CoA synthases (thiokinases) in the cytosol. For the mitochondrial transport of long-chain fatty acids the mtOM-enzyme carnitine palmitoyltransferase I (CPT-1; rate-limiting step in FAO) is required which generates an acyl-carnitine intermediate from acyl-CoA and carnitine. In the next step, an integral mtIM protein carnitine-acylcarnitine translocase (CACT) catalyzes the entrance of acyl-carnitines into the mitochondrial matrix in exchange for free carnitines. In the inner side of the mtIM, another enzyme carnitine palmitoyltransferase 2 (CPT-2) converts the acyl-carnitines to carnitine and acyl-CoAs, which undergo ß-oxidation in the mitochondrial matrix. Short- and medium-chain fatty acids do not require the carnitine shuttle for mitochondrial transport. Octanoate, but not palmitate, (eight- and 16-carbon saturated fatty acids) may pass the mt-membranes, but both are frequently supplied to mt-preparations in the activated form of octanoylcarnitine or palmitoylcarnitine.

Hydrogen peroxide
Hydrogen peroxide
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.
Hydrogenion fluxVolume-specific hydrogenion flux or H+ flux is measured in a closed system as the time derivative of H+ concentration, expressed in units [pmol·s-1·mL-1]. H+ flux can be measured in an open system at steady state, when any acidification of the medium is compensated by external supply of an equivalent amount of base. The extracellular acidification rate (ECAR) is the change of pH in the incubation medium over time, which is zero at steady state. Volume-specific H+ flux is comparable to volume-specific oxygen flux [pmol·s-1·mL-1], which is the (negative) time derivative of oxygen concentration measured in a closed system, corrected for instrumental and chemical background. pH is the negative logarithm of hydrogen ion activity. Therefore, ECAR is of interest in relation to acidification issues in the incubation buffer or culture medium. The physiologically relevant metabolic H+ flux, however, must not be confused with ECAR.
