The alamarBlue® cell proliferation assay is based on a reducing environment that indicates metabolic active cells. Active cells are able to convert resazurin into the resorufin. Resazurin is blue and ...

In this simplified diagram of gram staining, bacterial cells are first treated with a purple dye called crystal violet. The dye gets into the cells’ peptidoglycan layer (gray), tinting it purple.

Bacteria that undergo cell death lose their adherence within the biofilm and are washed away before the staining process, reducing the amount of crystal violet staining in a culture. 200 µL 0.1% ...

One of the first staining assays used in biofilm analysis was the crystal violet assay. ... distinguish between living and dead cells. Therefore, several different staining techniques have ...
