A hemolytic plaque assay is a technique
used to show that certain antibodies
are secreted by antibody-making cells when these cells are mixed with red blood cells
. The mixture is spread onto a plate of agar
; if a plaque
appears, it means that the red blood cells have been destroyed (by hemolysis
) by the antibodies.
