title: A Trypanosoma cruzi monoclonal antibody that recognizes a superficial tubulin-like antigen.
abstract: A monoclonal antibody (MAB 10), obtained from mice infected with Trypanosoma cruzi, was found to recognize a superficial antigen in living or fixed parasites. It reacted more strongly with T. cruzi than with related parasites such as T. brucei and Leishmania. In immunoblots it recognized a single trypanosoma polypeptide and also brain tubulin, both of which had the same electrophoretic mobility. Further analysis suggested that the alpha-tubulin subunit contained the epitope recognized by MAB 10. These results suggest that a surface tubulin-like protein is present is T. cruzi.
