Question

Quizplus · Accepted Answer

The decolorizer in staining techniques, such as the Gram stain, is typically ethanol or acetone. Its role is to remove the primary dye from certain types of cells (e.g., Gram-negative bacteria) after they have been stained, allowing them to be counterstained with a different color, thereby differentiating them from other types of cells (e.g., Gram-positive bacteria).
