A Covalent Binding Index, CBI (flmol AF/mol DNA-P)/(mmol AF/kg b. w.) = 8,500 was found. Pretreatment of rabbits with AF coupled to bovine serum albumin in Freund's adjuvant led to the production of AF-directed antibodies. Administration of [3H]AF to such immunized rabbits resulted in a CJH of only 2,500, i.e., the iiDJ{.lUnization provided a protection by a factor of more than 3. Although this is encouraging evidence for the potential of active immunization against genotoxic carcinogens, a nurober of pointswill have to be clarified, such as the time course for the DNA binding and the question of a possible shift to other target cells.}, subject = {Krebs}, language = {en} }
