title: Virion and soluble antigens of japanese encephalitis virus.
abstract: Japanese encephalitis virions contain a 58 X 10-3-molecular-weight envelope glycoprotein antigen that can be solubilized with sodium lauryl sulfate and separated from other virion structural polypeptides and viral ribonucleic acid by gel filtration chromatography. The 58 X 10-3-molecular-weight envelope protein is the major antigen responsible for cross-reactivity of the virion in complement fixation tests with other closely related arboviruses. A naturally occurring soluble complement-fixing antigen is found in Japanese encephalitis mouse brain preparations after removal of particulate antigens. After partial purification by gel filtration and isoelectric focusing, the 53 X 10-3-molecular weight soluble complement-fixing antigen is more type specific than the Japanese encephalitis envelope antigen in complement fixation tests. Further, the Japanese encephalitis soluble complement-fixing antigen is stable to treatment with sodium lauryl sulfate and 2-mercaptoethanol, whereas virion complement-fixing antigens are unstable after this treatment.
