Nikon Eclipse Ti2 spinning disk confocal/Widefield/TIRF/SMLM microscope

The microscope is highly modular and can be used for different common microscopy techniques in both fixed and live samples. Is is funded through the NRC NORBRAIN infrastructure and also part of the NORBRAIN nanoscopy facility.

System spesifications

Lasers

For widefield fluorescens and CrestOptics X-Light V3 spinning disk confocal: Lumencor Celesta Quattro, 4 channels; 405 nm, 477 nm, 546 nm and 640 nm 

For TIRF and activation/bleaching experiments: LUN-F laser unit with 405 nm (70 nW), 488 nm (70 mW), 561 nm(60 mW) and 640 nm (50 mW) lasers.

Objectives

NA= numerical aperture WD= working distance in mm

  • 10x Air Plan Fluor NA0,30 WD 15,2 Phase contrast (Ph1)
  • 20x Air Plan Fluor (coverslip correction) NA0,45 WD 7,4 Phase contrast (Ph1)
  • 20x Air Plan Apochromat lambda NA0,75 WD 1,0 Fluorescence

  • 60x Oil CFI Apo TIRF (coverslip and temperature correction) NA1,49 WD 0,12 TIRF / fluorescence
  • 100x Oil CFI Plan Apochromat lambda NA1,45 WD 0,13 Fluorescence
Detectors

Camera based system: 

  • For any fluorescence detection: Monochrome Prime BSI Express Scientific CMOS 
  • For brightfield color staining: DS-Fi3 CMOS.
Live cell imaging
  • In general very well suited for live cell timelapse (fast, long term, multi-positions).
  • OkoLab stage top heating incubator with CO2 control.
  • Perfect focus system (PFS).
  • Possible to set up multi-positions over time. 
  • Bleaching (FRAP) and activation (PA) experiments.  
TIRF

Total Internal Reflection Fluorescence uses an evanescent wave from total internal reflection to excite fluorescence only within ~100–200 nm of a surface. This enables high-contrast imaging of processes at cell membranes.

SMLM

Single-Molecule Localization Microscopy is a super-resolution technique that localizes individual fluorescent molecules to reconstruct images beyond the diffraction limit. This system is rigged to accommodate the following applications:

  • Single partical tracking (spt-PALM)
  • PALM (Photo Activated Localization Microscopy)
  • DNA-Paint 

Support on these applications are handled through NORBRAIN, not MIC.
