Abstract
Advanced glycation end products (AGEs) are a heterogenous group of glycation adducts on amino acids produced with sugars or dicarbonyls. Intracellular inflammation triggered by binding of AGEs to receptor for AGEs (RAGE) is linked to some chronic diseases. Here, we established a competitive assay format to comprehensively quantify AGEs which bound to RAGE. RAGE-binding activities of sugar- and dicarbonyl-derived AGEs were correlated with oxidative stress in cultured cells generated by the respective AGEs, suggesting that this would be a promising method for evaluating AGEs which could affect cellular functions despite limited information on individual glycation adducts.
