Abstract

A PrP gene, from a Korean bovine, exhibiting a nonsense and a missense polymorphism respectively at nucleotides 576 and 652 has been cloned. The latter resulted in Glu to Lys substitution at amino acid residue 218. After expression and purification of the recombinant bovine PrP (recBoPrP) with Glu218Lys substitution, a polyclonal antibody against this protein was raised. ELISA and Western blot analysis suggested that the recBoPrP obtained in this study had a unique conformation not presented in native PrPC, and the polyclonal antibody recognized PrP in a conformation dependent manner. These reagents will be valuable tools for studying PrP conformation.
