Figure 3

Immunoblot analysis visualizing the secretion of different PE35/PPE68_1 variants containing an HA-tag at the C-terminus of PPE68_1, using cell pellets (P) and culture supernatant (S) of WT M. marinum (A), eccCb1 mutant (B) and espG1 (C) strains. GroEL2 and EsxA were used as loading controls. Equivalent OD units were loaded; 0.2 OD for pellet and 0.5 OD for supernatant fractions.
