Fig. 2From: Label-free quantitative proteomic analysis of the inhibition effect of Lactobacillus rhamnosus GG on Escherichia coli biofilm formation in co-culturea Venn diagram summarising the common and differentially expressed proteins before and after coculture. b Hierarchical cluster of proteins differentially expressed in (a) E. coli before coculture (group C) and after coculture (group A), and (b) LGG before coculture (group D) and after coculture (group D). Red represents high expression and blue represents low expression. Two main clusters of proteins can be observed, one upregulated (right) and the other downregulated (left)Back to article page
