Tag: Carbohydrate detection

According to BOC Sciences, the Periodic Acid-Schiff (PAS) stain is the most widely used technique for detecting carbohydrates like polysaccharides and mucins in tissue sections, producing a vibrant magenta color. This guide explores not only the common PAS stain but also other chemical reagents and advanced fluorescent dyes used to answer the question of what dye is used for carbohydrates.

Over a century ago, Hans Molisch discovered a chemical test that is still widely used today to screen for the presence of carbohydrates. The most common general test to detect carbs is Molisch's test, which indicates a positive result with a purple ring at the interface of two layers.
