## Abstract

The circulating advanced glycosylation endproducts Hb-AGE, serum AGE-peptides and urinary AGE-peptides are disclosed as long term markers of diseases and dysfunctions having as a characteristic the presence of a measurable difference in AGE concentration. Diagnostic and therapeutic protocols taking advantage of the characteristics of these AGEs are disclosed. Antibodies which recognize and bind to in vivo-derived advanced glycosylation endproducts are also disclosed. Methods of using these antibodies as well as pharmaceutical compositions are also disclosed, along with numerous diagnostic applications, including methods for the measurement of the presence and amount of advanced glycosylation endproducts in both plants and animals, including humans, as well as in cultivated and systhesized protein material for therapeutic use.
