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.
Diagnostic Methods
Technology
Laboratory test involving interaction of antigens with specific antibodies.
Diagnostic Methods
Technology
Antigen aggregation with antibody, in the right ratios, to cause precipitation.
Diagnostic Methods
Technology
A flow cytometry technique that utilizes mass spectrometry to detect antibodies labeled with heavy metal ion tags that are bound to antigens of interest on single cells.
Diagnostic Methods
Technology
A type of enzyme immunoassay that uses antigen-coated microparticles as a substrate for antibody binding.
Diagnostic Methods
Technology
A quantitative technique used to detect and estimate the concentration of an antigen by measuring the diameter of the ring of precipitation (precipitin ring), which is formed as a result of the interaction of the antigen and an antibody at optimal concentration.
Diagnostic Methods
Technology
Radioimmunoassay (RIA) is an immunological technique, which quantitatively determines antigen and antibody concentrations, using a radioactively labeled substance (radioligand), either directly or indirectly.
