【Abstract】 Objective To compare soluble proteins of the seven strains of Trichomonas vaginalis from the mainland of China(Beijing, Tangshan, Chengde, Jiujiang) and determine their similarities and/or differences. Methods Soluble proteins of the seven strains of T. vaginalis were analyzed by SDS-polyacrylamide gel eletrophoresis and VDS Gel Documentation Analysis System for understanding T. vaginalis biological property. Results A total of 18-24 distinct protein bands were demonstrated, 15 bands were common in seven isolates. Molecular weights (MWs) of 2-6 bands were more than 100 ku, The ranges in MWs of other proteins were 16-97 ku. Conclusion Similarity was observed in protein profile among different isolates, while total protein bands were of difference.更多还原
