Insights

Immunohistochemistry and immunocytochemistry are powerful research and diagnostic tools. Careful consideration of technical modifications and antibody choices is crucial to avoid misinterpretations in molecular probing.

Area of Science:

  • Immunohistochemistry and immunocytochemistry as in situ molecular probing techniques.
  • Applications in immunology, pathology, cell biology, embryology, cell kinetics, and carcinogenesis research.
  • Utilizing polyclonal and monoclonal antibodies for specific target detection.

Context:

  • Methodology appears straightforward but presents practical challenges.
  • Commercial kits can mask underlying technical difficulties.
  • Critical evaluation of technical modifications is essential.

Purpose:

  • To highlight the versatility and potency of in situ molecular probing.
  • To address the practical difficulties encountered in immunohistochemistry/immunocytochemistry.
  • To emphasize the importance of reagent selection, including antibody types.

Summary:

  • Immunohistochemistry and immunocytochemistry are potent in situ molecular probing methods with broad applications.
  • Despite theoretical simplicity, practical execution involves significant challenges.
  • Uncritical use of kits and improper reagent selection, including antibodies, can lead to spurious results and misinterpretations.

Fixation and Sectioning

Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Immunofluorescence 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.

Immunocytochemistry 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.

Immunogold 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.
