title: Isolation of a monoclonal antibody which blocks vaccinia virus infection.
abstract: We have isolated a monoclonal antibody, B2, that neutralizes vaccinia virus infection. B2 reacts with a trypsin-sensitive cell surface epitope. B2 does not neutralize infection of herpes simplex virus, suggesting that the B2-reactive epitope is specifically involved in vaccinia virus entry. A survey of 12 different cell lines reveals a correlation between B2 reactivity and susceptibility to vaccinia virus infection. In addition, B2 interferes with vaccinia virus adsorption to target cells. Taken together, the B2-reactive epitope is part of a receptor that appears important for vaccinia virus entry.
