Identification of SjSP-13 peptides recognized in sera from schistosomiasis patients. a Reaction of 10 human serum samples (seven infected samples and three uninfected samples from healthy individuals) to the 17 GST-peptide-His fusion proteins determined by chemiluminescent ELISA. R = (RLUs of GST-peptide-His – RLUs of PBS)/ (RLUs of GST-His – RLUs of PBS). GST-peptide-His with R ≥ 2 were considered as seropositive reaction. Abbreviations: RLUs, relative light units; HA, hemagglutinin tag-GST fusion protein. b The recognition of p7 and p8 by the representative serum samples of Patients 1, 2 and 7 was confirmed by Western blot
