Immunochemistry is also used to describe the application of immune system components, in particular antibodies, to chemically labelled antigen molecules for visualization. Various methods in immunochemistry have been developed and refined, and used in scientific study, from virology to molecular evolution. Immunochemical techniques include ...
Immunohistochemistry can be performed on tissue that has been fixed and embedded in paraffin, but also cryopreservated (frozen) tissue.Based on the way the tissue is preserved, there are different steps to prepare the tissue for immunohistochemistry, but the general method includes proper fixation, antigen retrieval incubation with primary antibody, then incubation with secondary antibody.
Micrograph of a GFAP immunostained section of a brain tumour.. In biochemistry, immunostaining is any use of an antibody-based method to detect a specific protein in a sample. . The term "immunostaining" was originally used to refer to the immunohistochemical staining of tissue sections, as first described by Albert Coons in 1941.

Immunofluorescence is a widely used example of immunostaining (using antibodies to stain proteins) and is a specific example of immunohistochemistry (the use of the antibody-antigen relationship in tissues). This technique primarily utilizes fluorophores to visualize the location of the antibodies, while others provoke a color change in the ...
The techniques produce those lines on different types of graphs. The techniques and their graphs are: Measuring circles while all are expanding (kinetic method): graph charting logarithms of initial antigen concentrations vs. diameters of precipitin circles on a best-fit semi-logarithmic plot .
The terminologies, immune-methods and immune-chemical techniques refer to a variety of immunoelectrophoresis processes whose results are identified using antibodies and immunological methodologies. [4] As a result, immunomethods' great sensitivity is a beneficial compared to the great expense of utilizing antibodies.
