From: Surface-associated MUC5B mucins promote protease activity in Lactobacillus fermentum biofilms
Two-dimensional gel-electrophoresis of surface proteins from Lactobacillus fermentum . Proteins isolated from bacteria in a MUC5B-environment (left) or a nutrient broth environment (right) were subjected to IEF in a pH 4–7 gradient followed by SDS-PAGE in 14% gels. Gels were silver-stained and image analysis of differently expressed proteins performed using Delta 2D software.
