WebFollowing incubation, the monolayers are then microscopically examined, and the cell layer reactivity is scored for any abnormal cell morphology and cellular degeneration. Cells are scored for reactivity at 24–48 h on a grading scale: 0 = no reactivity, 1 = slight, 2 = mild, 3 = moderate, 4 = severe reactivity. In vitro (meaning in glass, or in the glass) studies are performed with microorganisms, cells, or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates.
