TcNatC and TcNatA protein interaction. (a) Immunoprecipitation (IP) of TcNaa30. The parasite lysate was incubated with anti-TcNaa38. As a control, the lysate was incubated with rabbit sera (preimmune). The blot was analyzed with anti-TcNaa30. Molecular weight marker in kDa is indicated. (b) Coimmunoprecipitation assays of TcNaa10 with TcNaa15 protein. IP with preimmune sera was used as a control. Western blots of the immunoprecipitated samples were probed with rabbit anti-TcNaa10 and anti-TcNaa15.
