The Schaeffer–Fulton stain is a technique designed to isolate endospores by staining any present endospores green, and any other bacterial bodies red. The green stain is malachite green, and the counterstain is safranin, which dyes any other bacterial bodies red.
Famous quotes containing the word stain:
“It is extraordinary how the house and the simplest possessions of someone who has been left become so quickly sordid.... Even the stain on the coffee cup seems not coffee but the physical manifestation of ones inner stain, the fatal blot that from the beginning had marked one for ultimate aloneness.”
—Coleman Dowell (19251985)
