The Penn Dental Medicine Live Cell Imaging Core features a Nikon A1R Confocal Microscope, that includes the following specifications and applications.

  • Transmitted light, DIC and epifluorescence (Dapi, FITCTRITC filters)
  • Objectives: 20x Dry, 40x Dry, 60x water, 100x oil
  • Fully automated XYZ scanning stage — Piezo Z stage insert for high speed image capture when using resonance scanner; Perfect Focus System, allowing for accurate stage reposition over timed series events.
  • Environmental chamber — Adjustable CO2 percentage and temperature with constant humidity; Accommodates 35 mm glass bottom culture dishes, 30×60mm chamber slides and 25×75mm glass slides.
  • Scan Heads for Image capture — Galvo (up to 4 fps (512×512); Resonance 30 fps (512×512 up tp 230 fps (512×64)
  • Stage — Fully automated XYZ scanning; Piezo Z stage insert for high speed image capture with resonance scanner; Perfect Focus System, allowing accurate stage reposition over a time series.
