Could other dyes be used as a counterstain?
Yes, other dyes can be used as counterstains in histology and microbiology to enhance the contrast between the target tissue or cells and the background. Common counterstains include eosin, methylene blue, and hematoxylin, which are used in combination with primary stains like hematoxylin and eosin staining. Different counterstains can provide different color contrasts for better visualization under the microscope.
