Technology
The use of acid-fast stain to examine a specimen for the presence of acid-fast microorganisms, specifically mycobacteria.
Technology
A process where a rotating machine exposes a specimen to centrifugal force. This process can be used to remove moisture from a specimen, to subject an organism to increased gravitational forces, or to separate the components of heterogeneous mixtures based on density differences.
Technology
A measurement of the antibody or complement-coated erythrocytes in a blood specimen in vivo.
Technology
Any form of microscopy in which the interactions of electrons with the specimens are used to provide information about the final structure of that specimen.
Technology
Immunohistochemical staining techniques allow for the visualization of antigens via the sequential application of a specific antibody to the antigen (primary antibody), a secondary antibody to the primary antibody and an enzyme complex with a chromogenic substrate. The enzymatic activation of the chromogen results in a visible reaction product at the antigen site. The specimen may then be counterstained and coverslipped. Results are interpreted using a light microscope and aid in the differential diagnosis of pathophysiological processes, which may or may not be associated with a particular antigen.
Technology
An imaging technique that uses multiple photons to absorb infrared light, thereby minimizing phototoxicty and photobleaching, making it an ideal method for imaging living specimens, especially those involving deep tissue.
Technology
Technique of electron microscopy in which the specimen is coated with heavy metal and then scanned by an electron beam. The resolution is not as great as with transmission electron microscopy, but preparation is easier (often by fixation followed by critical point drying), the depth of focus is relatively enormous, the surface of a specimen can be seen (though not the interior unless the specimen is cracked open) and the image is aesthetically pleasing.
Technology
An electron microscopy imaging technique that is utilized to examine structural components of a sample by passing electrons through the specimen.
