The method leading to overexpression of the full-length mouse recombinant prion protein (mrPrP 23-231) in the cytoplasm of E. coli as a his-PrP fusion protein and its effective purification using affinity chromatography is described. A typical yield of the method was 8-10 mg his-mrPrP per L of the bacterial culture. The purity of purified protein was > 95 %. The purified his-mrPrP was converted to a soluble form and its folding to alpha-helical and beta-sheet conformations was studied. The properties of differently folded mrPrP were determined by measuring their circular dichroism spectra, partial resistance to cleavage by proteinase K and by centrifugation in sucrose gradient.
