VisiScope Confocal Cell explorer

IMG_0727

  • The VisiScope Confocal Cell Explorer is a fluorescence imaging system combining epi-fluorescence and spinning disk confocal microscopy.
  • Two PCO Edge sCMOS 5.5 cameras on a beam-splitter, enable this setup to acquire two channels at the same time (Dual-Cam Mode). The combination of 5 lasers, several dual-, triple- and singlepass filters, a HXP-120 metal-halid fluorescent lamp and a set of 6 objectives as well as the Nikon Perfect Focus System, a X-Y-motorized stage with a Ludl NanoPrecision Z-stage for fast optical sectioning and a heat and CO2 controlled incubator, allow very advanced long term automated high-throughput live imaging on this setup.

This imaging system is used for very long time-lapse imaging (up to 6 days) of 2D and 3D cell cultures. Programs allow combinations of short periods of fast time-lapse imaging with longer periods of slow time-lapse imaging. This enables the imaging of highly dynamical events in single cells (e.g. the movement of vesicles) over short periods of time and slow events (e.g. cell cycle) over long periods of time.
