Samples 1 and 2 were obtained by transfection with pDL553. Sample 3 was from a cell line stably transfected with HDV cDNA (12). Samples 4 and 5 were obtained from infected woodchucks (40). Samples 6 and 7 were obtained from mice that had been transfected with HDV cDNA by a hydrodynamics-based procedure (7).
