<p>In order to produce hepatitis B virus (HBV) surface proteins in the form of particles with substantially reduced entrapped carbohydrate content, DNA encoding the HBV surface proteins was expressed in a recombinant yeast host which is deficient in its ability to glycosylate proteins. These HBV surface proteins display the antigenic sites genetically encoded by the S domain of the HBV virion envelope open reading frame and contains substantially reduced levels of entrapped carbohydrate when compared with HBsAg particles produced in 'wild-type' yeast cells. These particles are useful as a vaccine for both the active and passive treatment or prevention of disease and/or infection caused by HBV or other agents serologically related to HBV.</p> |
