  5. 5. High-performance liquid chromatography for analysis of 32P-postlabeled DNA adducts

    Författare :Magnus Zeisig; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :DNA adducts; 32P-postlabeling; HPLC; method development;

    Sammanfattning : The formation of DNA adducts, i.e. the covalent binding of chemicals and chemical groups to DNA, is believed to be an important step in chemical carciogenesis. DNA adducts are usually formed at very low levels which requires very sensitive methods to analyze them. LÄS MER
