Figure 4. Antibodies that stain the parasitophorous vacuole.
A) Phase contrast and IFA of a group of antibodies that appear to stain small circular membraneous blebs within the vacuole (inset and arrowheads) and also have some parasite membrane staining. B) 21H7A and 4A4 stain the parasitophorous vacuole characteristic of dense granule proteins.
