EmIR1 electron microscopic analyses. The anti-EmIR1 antiserum and gold-coupled anti-rabbit antibodies were used to detect EmIR1 in the metacestode germinal layer. A) Overview showing the location of the laminated layer, the germinal layer, undifferentiated (stem) cells and glycogen storage cells. B) Glycogen storage cell showing massive anti-EmIR1 staining (arrows). Scale bar in larger image represents 0.6 μm, scale bar in insert represents 3.6 μm.
