ABSTRACT
The glycoprotein of infectious hematopoietic necrosis virus was truncated to ten overlapping fragments. All fragments were displayed on the inner membrane of the Escherichia coli periplasm. After disruption of the outer membrane, spheroplasts that had anchored with the glycoprotein fragment were incubated with an anti-glycoprotein polyclonal antibody. Prey pairs were detected and quantitated by flow cytometry with all fragments but one, G2, reacting with the polyclonal antibody. The antigenicity of all ten fragments was analyzed using conventional methods, and epitopes were localized in all fragments, except for G2 and were consistent with FCM analysis. Antigenicity of purified glycoprotein fusion proteins was confirmed by western blotting and ELISA. This method provides a rapid, quantitative and simple strategy for identifying linear B cell epitopes of a given protein.
