WebBiofilms are formed when free-swimming, planktonic microbes adhere to one another and to a surface, and are often resistant to antibiotics. To test this antibiotic resistance, Emery Pharma offers a microplate peg lid-based Minimum Biofilm Eradication Concentration (MBEC) assay and crystal violet biomass staining assay in 96-well microplate format. WebThe bound cells were stained with 200 μl of 0.1 % (v/v) crystal violet (CV) solution for 10 minutes at room temperature. Excess dye was removed by washing each well (3X) with 200 μl of 0.85 % ...
