Testing Principle

Neutral mucus contains amino hexose and free hexose. Acid mucus also contains amino hexose and different kinds of acid radical. Neutral mucus is found in gastric mucosa, duodenum gland, submandibular gland and prostatic epithelium. Acid mucus is found in respiratory tract, goblet cells of digestive tract, aortic wall, cartilage matrix, cornea and skin. Gastric mucosa secretes neutral mucus. Acid mucus is secreted in intestinal metaplasia of stomach or intestinal type of gastric cancer. However, gastric type of gastric cancer secretes neutral mucus. Acid and neutral mucus is hardly distinguished in hematoxylin and eosin stain. With AB-PAS stain, acid mucus can be stained blue by Alcian stain. Neutral mucus can be stained red by PAS.
