Safranin O is a cationic dye, which displays less significant metachromasia. It is used to detect any variations in articular disease. Safranin O binds specifically to polyanions. It detects the amount of proteoglycan present in cartilages. Safranin O is used as a marker for glycosaminoglycan depletion in osteoarthritis. Safranin is used as a counter stain in gram staining.
Safranin O has been used in the histological analysis of femurs. It has also been used to detect the presence of glycosaminoglycans in the inner body of meniscus structures.
