Immunological methods have been proposed for the study of antigenic characterization using strains isolated from different patients. This work compares protease profiles from the different strains using gelatin containing polyacrylamide gels to analyse the protease activity. High molecular weight proteases (20 to 100 kDa) were found on gels showing quantitative differences. Human IgG antiproteases were detected by immunoblotting using the same extracts. These proteases could be related with T. vaginalis pathogenesis.177-181porgelatin-SDS-PAGEimmunoblottingproteasesTrichomonas vaginalisproteinasebrazilcontrolled studyhumannonhumanpolyacrylamide gel electrophoresistrichomonas vaginalistrichomoniasisArtigoAcesso restrito2-s2.0-0028790491
