ABSTRACT:
DNA constructs are provided of epitope-tagged proteins or protein fragments which are conveniently purified with immunoaffinity chromatography such as epitope-tagged prion proteins (PrP). Transgenic animals expressing an epitope-tagged protein are provided, including transgenic animals expressing epitope-tagged PrP. Methods for distinguishing between the conformational shapes of a protein and a convenient method for isolating a tagged protein by immunoaffinity chromatographic methods are provided.
