Supplementary Figure 5: SDS-PAGE comparison of cell envelopes without and with expressing PagL and T4SScc.
From: Probing a cell-embedded megadalton protein complex by DNP-supported solid-state NMR

Comparison of SDS-Page results of cellular envelope preparations without (- IPTG) and with (+ IPTG) PagL (a, Ref.) expression. b) Cell envelope preparation without (- tetracycline) and with (+ tetracycline) expression of T4SScc. We note that B7 only comprises 48 residues and it thus difficult to detect by Polyacrylamide gel electrophoresis (see also ref.). See also Supplementary Fig. 2.
