PG - 807-12 AB - Antibodies were elicited in rabbits immunized with a mixture of methylated bovine serum albumin and N-hydroxy-2-aminofluorene reacted DNA (DNA-AF). These antibodies were used in competition radioimmunoassays (RIA) with [3H]DNA-AF as radioactive antigen and different N-acetoxy-2-acetylaminofluorene (N-AcO-AAF) and N-hydroxy-2aminofluorene (N-OH-AF) reacted DNAs, deoxyguanosine, dGMP, dGpA and dApG as inhibitors. Based on the results of RIA it is concluded that the binding sites of the two residues, -AF and -AAF, to guanosine in DNA, are essentially the same. Moreover, the same sites seem to be reactive also in the direct reaction of N-AcO-AAF with dGMP. Circular dichroism measurements of modified DNA confirm the RIA results.
