In the Alcian blue mucosubstance protocol, what serves as the counterstain?

The main idea is that Alcian blue stains acidic mucosubstances blue, so a counterstain is used to provide contrast and reveal tissue architecture. Nuclear Fast Red is the classic counterstain for this protocol because it colors nuclei and other tissue elements pink to red, giving a clear contrast against the blue mucosubstances. This makes it easier to see where the mucosubstances are located within the tissue, such as in goblet cells or the basement membranes. Other stains like Eosin or Hematoxylin are not the standard pairing for Alcian blue mucosubstance staining, and Methylene blue isn’t typically used as the counterstain here.
