Patent number: 6379891Abstract: Viral proteins derived from an enterically transmitted non-A/non-B viral hepatitis agent (HEV) are disclosed. In one embodiment, the protein is immunologically reactive with antibodies present in individuals infected with the viral hepatitis agent. This protein is useful in a diagnostic method for detecting infection by the enterically transmitted agent. Specific epitopes have been identified that are reactive with sera of individual infected with different strains of HEV. Also disclosed are DNA probes derived from a cloned sequence of the viral agent. These probes are useful for identifying and sequencing the entire viral agent and for assaying the presence of the viral agent in an infected sample, by using probe-specific amplification of virus-derived DNA fragments.Type: GrantFiled: April 19, 2000Date of Patent: April 30, 2002Assignees: The United States of America as represented by the Department of Health and Human Services, Genelabs Technologies, Inc.,Inventors: Gregory R.

Patent number: 6214970Abstract: Antigens are provided which are derived from the enterically transmitted non-A/non-B viral hepatitis agent, known as hepatitis E virus (HEV). The HEV antigens and in particular, soluble species of the capsid protein encoded by the carboxy terminal region of HEV ORF2, are immunoreactive with sera from individuals infected with HEV. In one embodiment, these antigens may be produced by a baculovirus expression vector and form virus-like particles (VLPs). The antigens are useful as diagnostic reagents in diagnostic methods and kits for determining infection of an individual with HEV. The antigens are also useful in vaccine compositions effective in methods for preventing HEV infection.Type: GrantFiled: October 13, 1995Date of Patent: April 10, 2001Assignee: Genelabs Technologies, Inc.Inventors: Thomas R.
