| Research Abstract |
It has been proposed that formation and accumulation of advancedglycation end products (AGEs) in various tissues are involved in atherosclerosis,diabetic complications and aging-associated diseases. In order to determine AGEsaccumulation in various pathological tissues, immunological studies using monoclonalanti-AGE antibodies are highly effective. However, only a few of antibodies against AGEshave been established at present. Actually, it is not easy to prepare monoclonalantibodies that have high-affinity and high-specificity against AGEs, because of thediversity and heterogeneity of AGE structures and their small molecular sizes. Therefore,we have conducted protein-engineering approaches to develop recombinant antibodies withhigh affinity for various kinds of AGEs. In the present study, we have carried out phagedisplay experiments to prepare single-chain antibodies (scFvs) specific for one of AGEstructure, GA-pyridine
