Reactions with other peptide antisera demonstrated that multiple smaller virus-specified proteins were carboxy-terminally truncated forms of HDAg, and immunoprecipitation studies suggested that different forms of HDAg were present as heterologous complexes within the liver extract. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-73-1-183
