Fig. 6From: Molecular characterization of a 31 kDa protein from Trichinella spiralis and its induced immune protection in BALB/c miceCellular localization of rTs31 in IEC cells under confocal microscopy. The IEC cells were first co-incubated with rTs31, then reacted with anti-rTs31 serum, infection serum or pre-immune serum, and finally dyed with FITC-anti-mouse IgG conjugate. Propidium iodide (PI) stained cell nuclei in red. Scale-bars: 5 μmBack to article page
