特异性This antibody recognises the ring-opened structure that forms when DNA is alkylated by the anti-cancer drug melphalan and is then exposed to alkali. The alkali causes guanine bases alkylated at the N7 position to undergo a so-called ring-opening reaction and this antibody appears to recognise this structure, although recognition may be influenced by the neighbouring DNA sequence. The products of the ring-opening reaction are more resistant to depurination reactions than the original guanine adducts. This antibody was developed to improve detection of melphalan-DNA adducts through its ability to recognise the stabilised adduct. The Amp4/42 clone did not bind to alkali-treated control DNA or to DNA that had been alkylated with melphalan but not exposed to alkali. This antibody can be used for quantification of melphalan adducts in purified DNA by ELISA and for immunofluorescent detection of melphalan-DNA adducts in single cells.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent dilution.
