Cytoskeleton and membrane dynamics

Dynamic processes in membranes can be followed by epifluorescence microscopy using fluorescent probes and sCMOS cameras, but undesired out of focus fluorescence reduces the signal-to-noise ratio and image resolution.

Working on sub-second time scales, confocal microscopy is ideally suited to following membrane dynamics, since spatial resolution is increased by measuring only the fluorescence of focused thin sample sections, removing out-of-focus fluorescence. In 3D membrane structures, confocal microscopy allows the acquisition of consecutive scans at varying depths. These scans are then processed to obtain a 3D view of the sample.

The Aurox Visionary software has been specially developed for the acquisition of live cell imaging data using the Aurox Clarity LFC unit as part of a laser free confocal microscopy system.

Designed with simplicity and ease of use at its core, the software provides a single graphical user interface, which relates device and experimental settings directly to the connected instrument hardware.

The Visionary software provides for the optimisation and control of the instrument set-up and calibration followed by the set-up and image acquisition control of the confocal microscopy experiment.

Key features of the software:

  • Instrument set-up and calibration
  • Experiment set-up and control
  • Real time confocal image quality inspection tool
  • Supports a range of digital camera manufacturer sCMOS devices, including, PCO and Andor
  • Outputs data in OME Tiff format
