A highly sensitive and specific method for the detection of 06-methylguanine (O6-meG), O^-methylthymine (O4-meT), and CH-ethylthymine (O4-etT) has been established by combining prefractionation by high-performance liquid chromatography (III'IX '). '•'!' postlabeling, and immunoprecipitation by monoclonal antibodies (PREPI method). DNA was enzymatically hydrolyzed to 2'-deoxynucleoside-3'-mono...

Developments in chromato-polarography and the results obtained from its application to the analysis of mixtures of organic compounds are presented. The possibility of determining traces of organic impurities in organic substances by this technique is evaluated. The polarographic method is today one of the most important instrumental methods and has found wide application in analytical chemistry...
