Anti-YFV-E protein [7A]

9

This antibody binds a conformational epitope on the envelope protein of the yellow fever virus comprising aa 153-155 in domain I and aa 71 in domain II of the E protein contributing to the epitope.

The original antibody showed 50% and 100% neutralizing activity in plaque reduction neutralization assay (PRNT) against YFV strains 17D-204-WHO and Asibi at concentrations of approximately 1 microg/ml and 10 microg/ml respectively. The original antibody neutralized wild-type YFV strains of genotypes West Africa I (Nigeria 1987) and II (Asibi) and East/Central Africa (CAR 1986, Ethiopia 1961) with comparable efficiency in a PRNT on PS cells. In a competition ELISA using biotinylated scFv-7A, this antibody fragment competed for binding to YFV-17D virions with the other neutralizing antibody fragments. The original scFv version of this antibody was able to immunoprecipitate a 55-kDa protein, corresponding to the molecular weight of the envelope glycoprotein of YFV-17D virions (PMID: 15919103).
