Fig. 2From: Increased Levels of Advanced Glycation Endproducts in the Lenses and Blood Vessels of Cigarette SmokersAGE content in extracts prepared from the cataractous lenses of nondiabetic smokers (S) and nondiabetic nonsmokers (NS). AGE levels in supernatants (normalized for protein concentration) were determined using a competitive ELISA employing AGE-BSA as the coating and competing antigen and the values obtained converted to AGE Units as previously described (17). Values are expressed as mean ± SEM (n = 20 for nondiabetic nonsmokers; n = 17 for nondiabetic smokers). The p value compares AGE levels in extracts from non-smokers versus smokers.Back to article page
