title: Antigenic study of the protein from a defective strain of tobacco mosaic virus.
abstract: Soluble protein from the defective strain PM2 of tobacco mosaic virus can be recognized as antigenically distinct from the protein of the wild-type tobacco mosaic virus by Ouchterlony and immunoelectrophoretic analyses at temperatures below 37 degrees C. At these temperatures a polymerized state of protein with a characteristic antigenic structure is present in the wild-type virus; this structure is absent from the PM2 preparations. Above 37 degrees C the precipitin patterns for tobacco mosaic virus and PM2 appear identical.
