Fig. 1From: Molecular characterization of a Trichinella spiralis elastase-1 and its potential as a diagnostic antigen for trichinellosisSequence alignment of Trichinella spiralis elastase gene (XP_003377838.1) with other Trichinella species or genotypes. Clustal X and BOXSHADE were used to analyze the sequences, obvious differences were observed in different species/genotypes. Black shading represents the residues identical to TsEla, and grey shading shows the conservative substitutionsBack to article page
