The structural proteins of adenovirus-associated virus (AAV) types 1, 2, and 3 were analyzed by acrylamide gel electrophoresis. In each case, one major protein (C) and two minor proteins (A and B) were identified. Component C had an estimated molecular weight of 62,000 daltons, and the molecular weights of components A and B were found to be 87,000 and 73,000 daltons, respectively. Coelectropho...
