Conformationally correct expression of membrane-anchored Toxoplasma gondii SAG1 in the primitive protozoan Giardia duodenalis

Infect Immun. 2002 Feb;70(2):1014-6. doi: 10.1128/IAI.70.2.1014-1016.2002.

Abstract

To explore the possibility of expressing membrane-anchored exodomains of heterologous surface antigens in Giardia, a chimeric construct containing the Toxoplasma gondii SAG1 gene was made. The Giardia system is shown here to provide a means of generating correctly folded chimeric surface proteins in a native and unmodified form.
