CONFOCAL MICROSCOPE

Enhanced imaging of fluorescently labeled specimens using a LSM 510 META scanning confocal microscope

Lasers

  • Argon laser with excitation lines at 458, 477, 488, 514 nm
  • Green HeNe laser at 543 nm
  • Red HeNe laser at 633 nm
  • Coherent Chameleon ULTRA software tunable Titanium:Sapphire laser (680 - 1040 nm) for multi-photon excitation.

Microscope

Zeiss AxioPlan 2IE MOT upright motorized microscope, with the following objectives:

  • Plan 100x oil 1.4 n.a. Differential Interference Contrast (DIC)
  • Plan 63x 1.4 n.a. DIC
  • Plan Neo 40x oil 1.3 n.a. DIC
  • C-Apochromat 40x 1.2 n.a. DIC for fluorescence correlation spectroscopy
  • Achroplan 40x 0.8 n.a. water DIC for live cell work
  • Plan Neo 20x 0.75 n.a. DIC
  • Plan Apo 10x

System Resources 

  • Imaging of most standard fluorophores, in either single-photon or multi-photon modes.
  • Simultaneous fluorescent and DIC imaging of most samples
  • Heated, motorized stage for live cell imaging.
    • Real time measurements of cell migration, ion flux and metabolic profiling (NADH, FP)
  • META scanning module with 32 narrow wavelength band single-channel detectors that can be used for spectra-based experiments.
    • Separation of fluorophores with closely-spaced emission peaks by linear un-mixing
    • Generation of fluorophore-specific spectra
    • Background subtraction
    • Intensity based measurements of protein-protein interactions in live and fixed samples using FRET techniques
  • Fluorescence correlation spectroscopy (FCS).
    • Study of molecular dynamics in living cells
    • Generation of diffusion coefficients
  • Time-correlated single photo counting (TCSPC) using a Becker & Hickl spectroscopy system.
    • Lifetime-based measurements of protein-protein interactions in fixed and living samples using FRET/FLIM techniques
  • Software for FRET, FRAP and FLIM applications, ratiometric imaging, and complex time series experiments.

Additional Equipment

  • Total Internal Reflection Fluorscence (TIRF) imaging on an inverted Olympus microscope (488 nm excitation).
    • Single molecule bleaching and observations
    • High axial resolution renderings of the features and events on the plasma membrane in living cells
We strive to provide dynamic imaging services and training for researchers and students including; experimental design, image acquisition, analysis (including statistics and figure generation) and potential installation of specialized equipment to meet each investigators research needs.
