Fig.Ā 4From: Soluble polymorphic bank vole prion proteins induced by co-expression of quiescin sulfhydryl oxidase in E. coli and their aggregation behaviorsSecondary structural features of bank vole prion proteins. Far-UV circular dichroism spectra of soluble rBVPrP-109M and rBVPrP-109I are shown in red and black, respectively. All spectra were recorded at 25Ā Ā°C in 20Ā mM sodium citrate buffer pH 5Back to article page
