General description

Safranin O is a cationic dye, which displays less significant metachromasia. It is used to detect any variations in articular disease.[1] Safranin O binds specifically to polyanions.[2] It detects the amount of proteoglycan present in cartilages.[1] Safranin O is used as a marker for glycosaminoglycan depletion in osteoarthritis.[2] Safranin is used as a counter stain in Gram staining.[3]

Application

Safranin O has been used in the histological analysis of femurs.[4][5][6] It has also been used to detect the presence of glycosaminoglycans in the inner body of meniscus structures.[7]
