Summary

Automatically generated

We beschrijven hier methoden voor gevoelige en accurate kwantificering van de laesies 8-Oxo-7, 8-dihydro-2'-deoxyguanosine (8-oxodGuo), 1, n6-etheno-2'-deoxyadenosine (1, n6-dAdo) en 1,n2- etheno-2'-deoxyguanosine (1,N2-dGuo) in DNA. De methoden werden toegepast op de beoordeling van de effecten van de omgevings fijn stof (PM2,5) in weefsels (Long, lever en nier) van blootgestelde A/J muizen.
