Conventional antibody against Nepsilon-(carboxymethyl)lysine (CML) shows cross-reaction to Nepsilon-(carboxyethyl)lysine ( CEL): immunochemical quantification of CML with a specific antibody.

Immunological strategies for the detection of N(epsilon)-(carboxymethyl)lysine (CML), one of the major antigenic structures of advanced glycation end products (AGE), are widely applied to demonstrate the contribution of CML to the pathogeneses of diabetic complications and atherosclerosis. Recent studies have indicated that methylglyoxal (MG), which is generated intracellularly through the Embden-Meyerhof and polyol pathways, reacts with proteins to form MG-derived AGE structures such as N(epsilon)-(carboxyethyl)lysine ( CEL). In order to accurately measure the CML contents of the proteins by means of an immunochemical method, we prepared CML-specific antibodies since conventionally prepared polyclonal anti-CML antibody and monoclonal anti-CML antibody (6D12) cross-reacted with CEL. To prepare polyclonal CML-specific antibody, CML-keyhole limpet hemocyanin (CML-KLH) were immunized with rabbit and CEL-reactive antibody was removed by CEL-conjugated affinity chromatography. Monoclonal antibody specific for CML (CMS-10) was obtained by immunization with CML-KLH, followed by successive screening according to CML-bovine serum albumin (CML-BSA)-positive but CEL- BSA-negative criteria. Both polyclonal CML-specific antibody and CMS-10 significantly reacted with CML-proteins but not with CEL-proteins. It is likely therefore that these antibodies can recognize the difference of one methyl group between CML and CEL. Moreover, CMS-10 significantly reacted with BSA modified with several aldehydes and its reactivity was highly correlated with the CML content, which was determined by high performance liquid chromatography, whereas 6D12 showed a low correlation. These results indicate that CMS-10 can be used to determine the CML contents of modified proteins in a more specific way.[1]
