Detection limits ranging from to femtomole (fmol) adducts/µg DNA (Carmichael et al. , , ; Phillips et al. ) and from 40 to attomole (amol) total adducts/µg DNA (Schoket et al. ) have been Size: KB. This thesis study focused on the analysis of these human adducts by the 32P-postlabelling technique. In order to detect the effects of air pollution resulted from engine exhaust on the aromatic adduct levels, PAH-DNA adducts were analysed in peripheral blood lymphocytes (PBL) of 53 newspaper vendors working at high and low traffic areas.

Table I Methods for the detection of DNA adducts Nevertheless, the 32P-postlabelling assay has been shown to be the most appropriate method for the detection of most DNA adducts. Table I shows a brief overview of the most sensitive methods for carcinogen DNA adduct detection, which represent marked.

In experimental animal studies, the quantitation of DNA adducts has usually required the use of highly radioactive chemical carcinogens. However, a major breakthrough in detection methods occurred in the early s with the development of the 32P-postlabelling technique.

Today, at least 60 laboratories have employed and customized these methods. The detection and characterisation of DNA adducts can provide mechanistic information on mode of action for genotoxic chemicals and in this context is Cited by:   This is the first book devoted to postlabelling methods, an important new analytical methodology.

Postlabelling methods have a wide range of applications: these include studies of pathways of metabolic activation of chemical carcinogens, studies of oxidative damage to DNA, monitoring occupational exposure to carcinogens, the association between DNA adducts and disease, the Pages: Figure 1 shows typical DNA adducts and figure 2 illustrates adduct levels measured in mussels (Mytilus galloprovincialis) of the Venice lagoon over tissue samples (gills or digestive glands) from at least 5 mussels were tested in the 32 P-postlabelling assay, as described previously (Venier and Canova, ).More recently, improvements related to DNA purification (xg Cited by: 3.

Introduction. The 32 P-postlabelling assay is an ultrasensitive method for detecting carcinogen–DNA adducts that is applicable to a very wide range of DNA lesions (Gupta et al., ; Beach and Gupta, ; Randerath and Randerath, ; Phillips, ).It has been applied to a large number of studies in which human exposure to genotoxic agents has been by: 32 P-Postlabelling also enables the long-term persistence of carcinogen–DNA adducts to be monitored.

Thus 7,dimethylbenz-(a)anthracene adducts have been detected in mouse skin DNA 10 months after topical application of the compound (Randerath et al., ), and safrole–DNA adducts persist in mouse liver at least 4 months after intraperitoneal administration (Randerath et al., ).Author: D.H.

Knowledge of the nature and amounts of DNA adducts formed in vivo also. In molecular genetics, a DNA adduct is a segment of DNA bound to a cancer-causing process could be the start of a cancerous cell, or adducts in scientific experiments are used as biomarkers of exposure and as such are themselves measured to reflect quantitatively, for comparison, the amount of carcinogen exposure to the subject organism, for example rats or.

A new modification of the 32 P-postlabelling method was described for the analysis of lipophilic DNA in human tissues.

To isolate these DNA adducts the method applied nuclease P1 enrichment before labelling and butanol extraction after labelling, followed by high performance liquid chromatography (HPLC) separation and flow-through radioactivity by: Electron capture mass spectrometry (EC/MS) as a means of detecting DNA adducts was reviewed.

The general concept of DNA adduction and its physiological significance were summarized. The general history of the development of EC/MS for detecting DNA adducts was outlined. Electrophores and their role in DNA adduct detection were discussed. in human DNA the two assays measure identical adducts.

One of the problems in measuring DNA adducts is specificity, i.e. detection of a particular type of adduct using stringent structural criteria. This has been achieved for only a few human DNA adducts.

DNA adducts are typically formed in very low concentrations in vivo « fmol/pg DNA.
