Mucin shows which staining characteristics?

Explanation:
Mucin’s appearance in routine tissue staining is driven by its acidic, carbohydrate-rich makeup. Those acidic components attract the basic dye hematoxylin used in hematoxylin–eosin sections, so mucin-rich areas commonly stain blue, i.e., basophilic. While special stains can reveal other aspects—neutral mucins with PAS or acidic/sulfated mucins with Alcian blue or metachromasia with certain dyes—these are not universal features for all mucin. In standard practice, the most consistent characteristic you’ll observe is basophilic staining, which is why basophilic only is the best choice. If you need to detect various mucin types specifically, you’d use additional stains like PAS, Alcian blue, or AB-PAS.
