What does hematoxylin and eosin stain? Correct Answer-Hematoxylin (purple) stains basophilic structures. Examples: DNA, RNA, Ribosomes Eosin (pink) stains eosinophilic/acidiphilic structures. Examples: cytoplasm and collagen. Which stain detects carbohydrates? What color does it turn carbs? Correct Answer-Periodic Acid-Schiff Reactions stain carbohydrates magenta Alcohols -> aldehydes Schiff reagent reacts w/aldehyde = magenta color. What would you use to detect enzyme activity? What...
