ABOUT US

Laboratory of Fluorescence and Confocal Microscopy was established under the “Excellence Initiative – Research University” Program as a core facility laboratory at the Division of Anatomy and Neurobiology of the MUG. The Laboratory’s work involves outstanding specialists in fluorescence microscopy and confocal microscopy. The Laboratory’s research team has set as its goal the dissemination of advanced microscopic imaging, and thus supports staff and doctoral students in deepening their knowledge of microscopic techniques by providing access to specialized equipment.

OUR POTENTIAL

1. Zeiss LSM 880 confocal microscopy system with AiryScan super-resolution attachment interfacing with Zeiss Axio Imager.Z2 microscope

The system allows the analysis of preparations stained by histochemical and immunohistochemical methods (frozen sections, fixed cell cultures) prepared on basic slides of 25mm x 75mm size by a system based on a straight microscope that allows brightfield operation, using Nomarski contrast (DIC).

2. Zeiss AxioScan.Z1 histology slide scanner

Integrated system for automatic scanning of preparations stained by histochemical or immunohistochemical methods allows the use of different types of magazines for slides that can hold: up to 100 slides measuring 25 mm x 75 mm, up to 2 slides measuring 50mm x 75mm and 1 slide measuring 100mm x 75mm.

3. PALM Microbeam laser microdissection system working with AxioObserver microscope 7 Zeiss

System based on an inverted microscope with motorized objective turret holder with automatic recognition of installed lenses.

4. Olympus MVX 10 Olympus monoscopic microscope

Allows analysis of preparations stained by histochemical and immunohistochemical methods (frozen sections, fixed cell cultures) prepared on basic slides measuring 25mm x 75mm by a system based on a monoscopic microscope adapted to macroscopic object imaging (without the need for image assembly).

5. Nikon Eclipse E600 microscope with Nikon DS-Ri2 camera, Nikon, Japan

Allows analysis of preparations stained by histochemical and immunohistochemical methods (frozen sections, fixed cell cultures) prepared on basic slides of 25mm x 75mm size by a system based on a simple fluorescence microscope.


SCOPE OF SERVICES

– morphological evaluation of biological specimens based on light microscopy methods, fluorescence microscopy and confocal microscopy,

– qualitative evaluation of preparations labeled by histochemical and immunocytochemical methods in single and multiple stains – with special emphasis on the cellular localization of the tested compounds,

– mapping of the tested compounds within the studied structures – analysis of the stained histochemical and immunocytochemical methods in staining single and multiple serial sections,

– quantitative analysis of selected morphological parameters using the methods of confocal microscopy,

– laser microdissection of fragments of frozen, paraffin-embedded preparations, single cells and cell fragments,

– cutting fresh and fixed tissue directly from slides,

– digital camera image acquisition, image file processing,

– recording of images in multiple formats, i.e. TIFF, JPG,

– possible editing to allow automation of processes,

– ability to create reports that include images and analysis results, creating custom report forms.
