Abstract
Two to five separate gel-precipitating (GP) antibody activities to sonicated measles virus cell pack antigen were detected by double immunodiffusion and immunoelectrophoresis of sera and CSF from patients with subacute sclerosing panencephalitis (SSPE). The major GP activity was identified as antibody to measles virus nucleocapsids , and a weaker activity as antibody to the virus hemagglutinin. The specificities of the other activities were not determined. Measles GP antibody activities of serum and CSF from patients with SSPE are carried by Ig[immunoglobulin]G proteins of restricted heterogeneity. Two separate and differently charged homogeneous IgG proteins with antibody activities to partially different measles nucleocapsid antigens were detected in about half the patients. The combined use of agarose electrophoresis and measles GP antibody immunoelectrophoresis of serum and CSF proved helpful in rapidly establishing the specific diagnosis of SSPE.Keywords
