The reaction of chloroacetaldehyde (CAA) with DNA results in the formation of ethenoadenosine also known as 1,N6-ethenodeoxy-adenosine or etheno-A. CAA is formed through metabolization of for example vinyl chloride, a well established carcinogen. In RNA, after in vitro activation, etheno-A and etheno-C are the principle products of RNA damage. Etheno derivate formation may be highest in single-stranded DNA-regions. The monoclonal antibody 1G4 reacts with both the ribose and deoxyribose form of the adduct. The antibody is not cross reactive with non-modified DNA or the normal nucleotides.
Flow cytometry, Frozen sections, Immuno assays, Immuno precipitation, Western blot
For immunohistology, flow cytometry and Western blotting dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:10.
