Fig. 5. Digestion of Pd-mP-globin in vivo. Partially engorged females were fed with serum enriched with 100 µmol l^–1 Pd-mP-globin for 12 h, as described in Materials and methods. Anterior midguts were fixed and embedded in methacrylate, and semi-thin sections were observed under a fluorescence microscope, as described under Materials and methods. (A) Two digest cells 2 h after feeding; (B) two digest cells 6 h after feeding. *Digestive vesicles; arrows, hemosomes; LU, intestinal lumen. Scale bar, 30 µm.
