Background
This antibody is suitable for the detection of bound and free pentosidine in tissues and tissue extracts. Long-term incubation of proteins with glucose leads, through Schiff's base and Amadori rearrangement products, to the formation of advanced glycation end products (AGE) which are characterized by fluorescence, brown color and inter- and intra-molecular cross-linking. Recent immunological studies using anti-AGE antibodies demonstrated the presence of AGE in (i) human lens, (ii) renal proximal tubules in patients with diabetic nephropathy and chronic renal failure, (iii) atherosclerotic lesions of arterial walls, (iv) ß2-microglobulin of carpal tunnel amyloid fibril deposits in patients with hemodialysis-related amyloidosis and (v) brain tissues of patients with Alzheimer’s disease. Pentosidine is one of the Maillard products, which were detected by Sell and Monnier (1989). Pentosidines have been shown to cross-link Arginine and Lysine residues. They were found in ß2-microglobulin of patients suffering from hemodialysis-related amyloidosis (Miyata et al., 1996). Reacts with pentosidine-HSA and free pentosidine in competitive ELISA.
