The protein contains the EBV early antigen protein fragment, amino acids: 306-390. The protein is purified by proprietary chromatographic technique.

Background: Epstein-Barr virus, frequently referred to as EBV, is a member of the gamma herpesvirus family and one of the most common human viruses. The virus occurs worldwide, and most people become infected with EBV sometime during their lives. It persists in B lymphocytes for the life of the host. IgG to the early antigen appears in the acute phase and generally falls to undetectable levels after 3 to 6 months. In many people, detection of antibody to the early antigen is a sign of active infection, but 20% of healthy people may have this antibody for years.

Specificity: Immunoreactive with all sera of EBV infected individuals.
