Technology
Frequently referred to simply as HPLC, this form of column chromatography is used frequently in biochemistry. The analyte is forced through a column by liquid at high pressure, which decreases the time the separated components remain on the stationary phase. Less time on the column then translates to narrower peaks in the resulting chromatogram and thence to better selectivity and sensitivity.

Technology
The study of cells and tissues using chemical staining techniques.
Technology
The microscopic study of characteristic tissue abnormalities by employing various cytochemical and immunocytochemical stains.
Technology
Affinity chromatography using monoclonal or polyclonal antibodies, or (less commonly) antigens, as the immobilized binding phase.
Technology
A method for the detection of proteins or antigens on samples of cells that are grown in monolayers or in suspension and deposited on slides using antibodies or other biomolecules that bind the target and can be visualized through a chemical process.
Technology
A quantitative technique used to detect and estimate the concentration of an antigen by measuring the precipitation which is formed as a result of the interaction of the antigen and an antibody at optimal concentration.
Technology
A laboratory testing method to determine the concentrations of immunoglobulins in the blood.
Technology
An enhancement of immunoelectrophoresis in which a series of post-electrophoretic gel slabs are layered with cellulose-acetate gels saturated with specific antibodies. The resulting antigen-antibody complexes fixed on the second gel may then be stained, allowing sensitive and specific qualitative visual identification of paraproteins by electrophoretic position. It can be used to identify specific proteins in the blood or urine. It has greatest application in the identification and monitoring of monoclonal proteins that are produced in conditions like Waldenstom's macroglobulinaemia and multiple myeloma.
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 immunological procedure in which antibodies are coupled with a peroxidase molecule. Following localization via the antibody, the peroxidase is reacted with a corresponding substrate to produce a product which can be seen with a light microscope.
