title: Composition of affinity-purified alpha-hemolysin of Escherichia coli.
abstract: Escherichia coli alpha-hemolysin was purified from culture supernatants by affinity chromatography, using a hemolysis-neutralizing monoclonal antibody ligand. Purified hemolysin contains several proteins and lipopolysaccharides. Thus, alpha-hemolysin exists as a macromolecular complex and may be exported from E. coli cells by outer membrane fragmentation.
