Figure 8From: Molecular characterization of a putative serine protease from Trichinella spiralis and its elicited immune protectionSubcellular localization of rTsSP bonding to IEC by confocal microscopy (×1000). The IEC was first incubated with rTsSP, secondly with anti-rTsSP serum (A), infection serum (B) or pre-immune serum (C), and finally with FITC-labeled goat anti-mouse IgG. Cell nuclei were stained using propidium iodide (PI) as red.Back to article page
