Production of a recombinant full-length prion protein in a soluble form without refolding or detergents

Abstract

Recombinant prion protein has been produced in insoluble form and refolded following solubilization with denaturants. It is, however, preferable to use a soluble recombinant protein prepared without artificial solubilization. In this study, a soluble recombinant prion protein was produced in Escherichia coli cells by coexpression of neuregulin I-β1 and purified to high purity.
