WebFor plating to a 100 mm plate, 100–200 µL of cell suspension generally works well. If very few colonies are anticipated, the entire cell suspension may be plated. However, if a very high number of colonies is expected, the cell suspension may be diluted up to 1:100 in S.O.C. medium before plating to avoid the formation of a bacterial lawn.
