Carbohydrate: Mucin
Mucicarmine Stain
Carbohydrate: Acid Mucin And Mucopolysaccharide
Fluorescent Acridine Orange Technique
used for the demonstration of glycogen specially when it uses the Diastase Method; may also stain
Mucoproteins, Mucin, Carbohydrates, Glycoproteins, Glycolipids, Unsaturated Lipids and Phospholipids. (+Red)
Periodic Acid Schiff
has a good affinity to glycogen (bright red) due to alkaline carminic acid ; weakly stains mast cell granules, fibrin and mucin
Best Carmine method
obsolete stain, not specific for glycogen, rapid but tends to fade after a few months
Langhan’s Iodine Method
gives a red-purple stain
Metachromatic Staining- Azure A metachromatic techniques and Metachromatic Toluidine blue
most popular method for acid mucin (+Blue)
Alcian Blue Technique
Neutral mucins are stained by PAS while acid mucin are stained by Alcian blue
Combined Alcian Blue-PAS-Hematoxylin technique
demonstrates sulfated mucins, staining it purple
Gomori’s Aldehyde Fuchsin
demonstrates mucin by adding aluminum hydroxide to carmine. (+) red
Mucicarmine stain
absorbed onto tissue containing acid mucin at low ph, and visualized by it’s conversion to
ferric cyanide.
Colloidal (Dialyzed) Iron technique
gives selective brilliant orange fluorescence. It is temporary and lasts for 2 hours once it is
mounted
Fluorescent Acridine Orange technique
