A high-throughput assay is being conducted in a 96 well plate to test compounds for anti-bacterial activity. Live bacterial cells are detected using “Live clear", a dye which is initially coloured blue, but turns clear in the presence of live bacterial cells. The control wells are shown below. Penicillin kills bacteria; glycerol does not affect them. Which of the control wells will appear blue at the end of the assay?
