Used in research to quantify pentosidine levels in biological samples such as serum, plasma, and tissue extracts. Helps assess the extent of advanced glycation end-product (AGE) accumulation in studies related to diabetes, aging, and chronic diseases like renal failure and osteoarthritis. Supports investigation into oxidative stress and protein cross-linking in connective tissues, cartilage, and bone. Commonly applied in clinical and preclinical studies to evaluate the effectiveness of anti-glycation therapies and antioxidants.
