Summary
Correlative microscopy combines multiple imaging techniques for enhanced specimen analysis. This study utilizes FluoroNanogold for high-resolution imaging of subcellular structures in human tissues.
Area of Science:
- Biophysics
- Cell Biology
- Microscopy
Background:
- Correlative microscopy integrates multiple imaging modalities to provide richer data than single methods.
- Commonly, fluorescence and electron microscopy are combined, often in cell culture systems.
- Applying correlative microscopy to tissue samples, especially human tissue, presents unique challenges.
Purpose of the Study:
- To adapt and apply correlative microscopy techniques to tissue samples.
- To demonstrate a method for high-resolution imaging of subcellular structures in human tissues.
- To utilize the bifunctional reporter FluoroNanogold for combined imaging.
Main Methods:
- Utilized ultrathin cryosections of tissue as a substrate for correlative microscopy.
- Employed the bifunctional reporter FluoroNanogold, which contains both a fluorochrome and a gold-cluster.
- Performed sequential fluorescence and electron microscopy on the same specimen sections.
Main Results:
- Successfully imaged exactly the same subcellular structures using both fluorescence and electron microscopy.
- Achieved a high level of spatial resolution in the correlative imaging of tissue samples.
- Demonstrated the utility of FluoroNanogold for correlative fluorescence and electron microscopy.
Conclusions:
- Correlative microscopy, particularly using FluoroNanogold, is effective for high-resolution subcellular analysis in human tissues.
- This approach overcomes limitations of cell culture-based correlative studies.
- Enables detailed examination of ultrastructure and localization within complex tissue environments.

01:12Immunofluorescence Microscopy
A fluorescence microscope uses fluorescent chromophores called fluorochromes, which can absorb energy from a light source and then emit this energy as visible light. Fluorochromes include naturally fluorescent substances (such as chlorophylls) and fluorescent stains that are added to the specimen to create contrast. Dyes such as Texas red and FITC are examples of fluorochromes. Other examples include the nucleic acid dyes 4’,6’-diamidino-2-phenylindole (DAPI), and acridine orange.

01:20Immunogold Electron Microscopy
Immunoelectron microscopy utilizes immunogold labeling of endogenous proteins with specific antibodies to detect and localize these proteins in cells and tissues. The procedure provides insights into the distribution and quantification of protein under different stimulation conditions offering clues about their functions. Conjugating highly electron-dense gold particles with primary or secondary antibodies allow antigen detection on and within cells, with high resolution and specificity.
01:22Immunocytochemistry and Immunohistochemistry
Immunocytochemistry (ICC) and immunohistochemistry (IHC) are techniques that use antibodies to check for specific proteins or antigens in a sample. The technique was first published by Albert Coons in 1941 to detect the presence of pneumococcal antigen in tissue sections from mice infected with Pneumococcus. Immunocytochemistry helps localization of proteins or antigens in individual cells like blood cells, stem cells, etc., while immunohistochemistry does the same for tissue samples.

Two-dimensional (2D) microscopy encompasses a range of optical techniques that capture images within a single focal plane, offering detailed representations of microscopic structures. These techniques are essential in biological and medical research, enabling the visualization of cellular and subcellular structures with different levels of contrast and specificity.There are several major types of 2D microscopy, each with strengths and applications.Bright-Field MicroscopyBright-field microscopy...
01:16Confocal Fluorescence Microscopy
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
01:37Super-resolution Fluorescence Microscopy
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been developed.
