This can be done with direct fluorescent antibody (DFA).

Depending on the virus, the plaque forming units are measured by microscopic observation, fluorescent antibodies or specific dyes that react with infected cells.

To evaluate the specificity of the Ogg1 antibody, slides were stained with fluorescent secondary antibody alone, which resulted in no background staining (data not shown).

FluoroSpot measures the secretion of several cytokines in each well by the use of fluorescent anti-cytokine antibodies.

Real mitotic cells can be visualized through the microscope by staining them with fluorescent antibodies and dyes.

Direct fluorescent antibody can also be used to detect parasitic infections, as was pioneered by Sadun, et al. (1960).

Yet another drawback is that they must be visualized with fluorescent antibodies, adding an additional step to processing.
