A comparison of polypeptides in measles and SSPE virus strains

Abstract

The polypeptide patterns of twelve subacute sclerosing panencephalitis (SSPE) and measles viruses have been compared by slab gel electrophoresis. The polypeptide patterns of nine strains of SSPE and measles virus were identical. Differences in the NP protein and the HA protein of the Oddo strain, the P protein of the large plaque variant of the Lec strain of SSPE and in the M protein of the Hu 2 measles strain could not be correlated with biological characteristics such as plaque morphology, origin or haemagglutination properties.
