Used in biomedical research to quantify dermatan sulfate levels in human tissue extracts, cell cultures, or biological fluids such as serum and urine. Enables researchers to study the role of dermatan sulfate in connective tissue disorders, skin aging, wound healing, and inflammatory diseases. Commonly applied in dermatological studies, glycobiology research, and clinical labs investigating metabolic or structural skin conditions. Provides a sensitive and specific method for detecting changes in dermatan sulfate concentration, supporting diagnosis and monitoring of diseases like Ehlers-Danlos syndrome or other sulfated glycosaminoglycan-related pathologies.
