Fig. 4From: Identification of antigens in the Trichinella spiralis extracellular vesicles for serological detection of early stage infection in swineBioinformatic analysis of Ts-TTPA. A Three-dimensional structural model of Ts-TTPA protein with secondary structure display. The alpha helix is covered in purple, the beta fold is covered in green, and the ring area is covered in gray. B Cladogram of analysis of Ts-TTPA. The maximum parsimony tree of tissue-type plasminogen activator protein in 12 species of Trichinella spiralis and Trichuris suis was drawn in MEGA. Protein sequence thumbnails of Ts-TTPA for each species are shown on the right. Different-colored squares represent different amino acidsBack to article page
