Figure 2 Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of partially purified bacteriocin-like inhibitory substance (BLIS) from Enterococcus faecium strain DSH20 after staining with Coomassie Brilliant Blue showed the molecular weight of approximately 35kDa. Line 1 shows a molecular mass marker (in kDa) and lines 2 and 3 show a molecular mass marker of purified BLIS with two repeats.
