2D electrophoresis of different fractions obtained from active and dormant M. tuberculosis cells. Each gel was stained by Coomassie followed by silver staining. (A) Cytosol fraction of active, early stationary phase cells. (B) Cytosol fraction of dormant cells after 4.5 months storage at room temperature (D1). (C) Cytosol fraction of dormant cells after 13 months storage at room temperature (D2). (D) Membrane fraction extracted by SDS of active, early stationary phase cells. (E) Membrane fraction extracted by SDS of dormant cells after 4.5 months storage at room temperature (D1). (F) Membrane fraction extracted by SDS of dormant cells after 13 months storage at room temperature (D2). The gel photo represents one out of two identical technical replicates.
