THE PROTEIN COATS OR "GHOSTS" OF COLIPHAGE T2

Abstract

A method of preparing the protein coats or ghosts of phage T2 is described along with proof that the lytic action is a property of the ghost. An assay based on the lytic action toward host cells has been developed which permits a rapid evaluation of the number of ghosts with a reliability of +/-15 per cent. The antigenic and certain physicochemical properties of the ghost have been determined.
