Confocal microscopy – equipment
Our Zeiss LSM 510 META is equipped with:
Light source = four lasers, with the wavelengths:
- DPSS 405 nm (excitation of e.g. DAPI, Hoechst 34580)
- Ar ion laser: 458, 477, 488, 514 nm (488 nm for excitation of e.g. Cy2, Alexa488, GFP, FITC)
- DPSS 561 nm (excitation of e.g. Cy3, Alexa 546 – Alexa 592, Texas Red, TRITC)
- HeNe ion laser: 633 nm (excitation of e.g. Cy5, Alexa633 - Alexa 647)
Detectors = two PMT:s (photomultiplier tubes) and a META detector.
Each detector has its own adjustable pinhole aperture, which allows for correction of different optical section thickness at different emission wavelengths.
Multiple laser lines and detectors allows simultaneous visualization of multiple fluorescent markers. In practice, however, you seldom use more than tree markers in a specimen.
The confocal microscope can be used with two different Zeiss epifluorescence microscopes. The scanning unit is mounted on an inverted microscope for routine use, as this setup is compatible with all standard microscope slides and many multiwell culture plates etc. For special applications the scanning unit can be moved to an upright fixed-stage microscope.
Both microscopes are equipped with high-quality optics, including water- or oil-immersion objectives with high numerical apertures.
