A
method of locating antigens in tissue, or of identifying
an antigen by the fluorescence resulting when the
antigenic material is exposed to a specific antibody
coupled with a fluorescent dye. The antigen-antibody
combination then is visible (luminous) using ultraviolet
light. This technique is used in the diagnosis of
syphilis, toxoplasmosis (a serious disease which
may lead to blindness and brain defects in the congenital
form, as well as myocarditis and other conditions),
and other diseases. |
