Fig. 1From: Identification of antigens in the Trichinella spiralis extracellular vesicles for serological detection of early stage infection in swineCharacterization and identification of Ts-ML-EVs. A The morphology and size of T. spiralis extracellular vesicles visualized by scanning electron microscopy. White arrow indicates the extracellular vesicles (scale bar 100 μM). B NTA shows the size distribution of T. spiralis extracellular vesicle by intensity. The illustration is a combination of histograms and peak charts. C Identification of marker proteins 14-3-3, enolase in the excretory-secretory product (40 μg) and extracellular vesicles (40 μg) of T. spiralis. D CD81 and CD63 were identified on the extracellular vesicles of T. spiralis by flow cytometryBack to article page
