Measuring Changes in Cellular Metabolism by Monitoring Extracellular Acidification and Oxygen Consumption in Real-Time

4 Jun 2017

The current technologies used to assess mitochondrial function via extracellular acidification and oxygen consumption rate are often designed in such a way that they ignore the impact of oxygen concentration on cellular bioenergetics. This application note describes using the CLARIOstar (with an atmospheric control unit) in conjunction with advanced dyes from Luxcel Biosciences to measure oxygen consumption and glycolytic flux in an open-flow respirometry system. It is found that this system enables measurement of respiration rate at steady state, where oxygen supplied equals oxygen consumed, providing a robust and efficient means of measuring cellular bioenergetics at oxygen concentrations which are physiologically relevant.

Microplate Readers / DetectorsMicroplate readers are used to automate the detection and analysis of labeled or label-free components in microplates during assays or live-cell monitoring. Microplate readers are generally distinguished by their mode of detection. Types include absorbance, luminescence, fluorescence intensity, fluorescence polarization, TRF / FRET and multimode microplate readers. Microplate readers deliver a high throughput of samples by reading multiple wells simultaneously, with the 96-well format the most commonly used. As a result, microplate readers are often used in the drug discovery, bioassays, research and pharmaceutical industries for screening applications. Microplate loading can also be automated, with robotic microplate stackers to increase throughput.

Plate processing systems include microplate handlers for moving plates, heat sealers, stackers and carousels for storage, retrieval and delivery, microplate washers and piercers. Useful features of plate processors include walk-away automation, compatibility and easy integration with microplate systems.FluorescenceThe emission of fluorescence occurs when a photon of energy is supplied to a fluorescent chemical compound by an external source, causing it to become excited. Fluorescence can be detected and measured for different purposes using microplate readers, fluorescence microscopes, fluorescence scanners, and flow cytometers.Fluorescence Based AssayFluorescence based assays are widely used in life science research and high-throughput screening to measure a broad range of cellular activities.Cell AnalysisThe analysis of cells allows researchers to understand the factors which contribute to cell health and function. These influencing processes can then be predicted and altered, leading to the development of medication and disease treatments.Cell BiologyCell biology studies the structure, function, and behavior of cells. Understanding cellular processes is essential for research in areas such as cancer biology, stem cell research, and neurobiology. Techniques like flow cytometry, microscopy, and cell culture enable researchers to explore cellular mechanisms in detail.
