more detail about this publication
"immunoperoxidase detection of the major surface proteins SAG1 and SAG2 revealed that they were distributed uniformly on the surface of extracellular tachyzoites. During invasion of the host cell the majority of the surface label failed to pass throught the tight junction. The label appeared to remain associated with membrane accumulating at the posterior of the zoite, where it was shed in the form of vesicles. This pattern of redistribution was observed with both surface molecules (Figs. 1, 4). However, in some in- stances, shedding of the surface coat was not complete and varying amounts of label were internalised and re- mained on membrane associated with or adjacent to the parasite surface "
