Congo red staining
For demonstrating expression of pleD, we used Congo red staining assay. As previous mentioned, high concentration of c-di-GMP could induce E. coli synthesize exopolysaccharides, and Congo red binding is a complex phenotype that reflects various outer membrane and surface properties including the presence of adhesive structures such as curli fimbria which are involved in biofilm formation. Wild type: DE3 contain pET28b plasmid, colony which was stained red color contain pET-pleD plasmid.
