Used in biomedical research to quantify keratin sulfate levels in biological samples, aiding studies on epithelial cell differentiation, skin disorders, and hair follicle development. Enables investigation of keratinocyte function and skin barrier integrity in conditions like psoriasis, eczema, and wound healing. Supports cosmetic and dermatological research by assessing the impact of formulations on keratin metabolism. Suitable for cell culture studies and tissue extracts where precise measurement of keratin sulfate is required.
