Czech-BioImaging offers access to a wide range of biological and medical imaging technologies:
Optical microscopy; macroscopic imaging of whole tissue or animal imaging; multiphoton deep penetration intravital imaging for obtaining 3D structure of thick specimens, tissues and live animals; high-throughput automated and semi-automated microscopy allowing statistical analysis of large amount of cells as well as their functional characteristics; high speed cell sorting providing the possibility for the isolation of the precisely defined cells, which can be used in further biological and biochemical assays, as well as for the statistical analysis of cellular responses; fast live cell imaging; long term live cell imaging for continuous observation to track slow or delayed cellular responses; combined physiological and optical imaging for a correlative study between cell and tissue activity and structure; non-invasive multi-modality imaging covering the scale from subcellular ultrastructures to the small animals; optical microscopy combined with simultaneous recording of electrical signals and/or electrical stimulations; small animal preclinical imaging; multimodal imaging of the particular animal; calibration of light microscopy systems; automated microscopy for acquisition of histology databases or genetic screens based on the expression of marker genes; imaging of plant systems; advanced incoherent holographic microscopy and robotic environment for quantitative evaluation of cell behavior.
Laser scanning confocal microscopy allowing sensitive spectrally-separated multichannel image acquisition, fast in vivo scanning, and optical sectioning of the live and fixed animal and plant specimens and thus giving access to 4D information about biological samples; high-end spinning disc microscopy with high sensitivity and spatiotemporal resolution allowing fast image acquisition with minimal photobleaching; functional imaging (FRET, FRAP, photoactivation) monitoring the microenvironment changes and molecular interactions in live cells and tissues with submicrometer spatial resolution and down to microsecond time resolution; fluorescence life time imaging (FLIM) and non-linear techniques based on second harmonic generation (SHG) - with unique image analysis support including development of custom-made SW implementation; single plain illumination microscopy (SPIM); 3D FPALM superresolution microscopy; super-sensitive visualizing and quantifying of PPI using FLIM-FRET; TIRF imaging used for cell membrane studies providing detailed insight into the structures located up to few hundreds nanometers from the glass – specimen interface. In vivo tracking of multiple molecules and processes; 3D reconstruction and localization of molecular processes; multimodal holographic microscopy as coherence-controlled holographic microscopy with fluorescence; polychromatic flow cytometry providing sensitive, high speed, multi-parametric fluorescence measurement of the large numbers of particles in the flow of sheath fluid.
