Differential staining refers to the type of staining that allows the analyst to tell different types of the cells apart; it is a general term that encompasses a variety of staining procedures. When an animal is broken down into its cells, the cells can vary in appearance and in function.
A differential staining technique (the Schaeffer-Fulton method) is used to distinguish between the vegetative cells and the endospores. The process is similar to the Gram stain in that there are four steps. A primary stain (malachite green) is used to stain the endospores.
