    Abstract
    A sensitive method has been developed for the visualization of nonradiolabeled glycosaminoglycan oligosaccharides resolved by polyacrylamide gel electrophoresis using fixation with azure A followed by staining with ammoniacal silver. This method, which can detect as little as 1-2 ng of a single oligosaccharide species, can be used to stain a few micrograms of a complex oligosaccharide mixture. The combination of gradient polyacrylamide gel electrophoresis and sequential azure A/silver staining can be applied to the analysis of all the complex glycosaminoglycans (i.e., heparin, heparan sulfate, chondroitin/dermatan sulfate, keratan sulfate) and hyaluronate, as well as to comparisons of specificities of the glycosaminoglycan-degrading enzymes. This procedure may be particularly valuable in situations where the availability of glycosaminoglycan is very limited and/or where radiolabeling is impractical or undesirable.
