摘要:
The cloning and sequencing of different polypeptides from the genome of a hepatitis C virus is disclosed. The polypeptides are prepared as non-fusion proteins in good yield. The polypeptide originating from the structure protein (core) is soluble under physiological conditions. Since the polypeptides have no foreign protein portions, they are preferably used in test kits and as vaccine.

In the area of virus diagnosis, in particular Epstein-Barr virus (EBV) diagnosis, methods for the detection of EBV and agents suitable for this purpose are provided, including peptides which are derived from p18-VCA and permit discrimination between acute and past EBV infection.
摘要:
The present invention concerns a polypeptide which is composed of the amino acids 1207±10 to 1488±10 of a hepatitis C virus and of less than 20 foreign amino acids and the use of this polypeptide as an antigen in an immunological test.

摘要:
Immunologically active peptides or polypeptides with a partial amino-acid sequence of the capsid proteins VP1 and VP2 of parvovirus B19 which permit tests to be carried out at low cost, sensitively and specifically for the determination of antibodies against human parvovirus B19 are made available. Short peptide sequences which, employed as antigen, serve to identify anti-B19 IgG-positive sera are identified. Furthermore, the production of these peptides using genetic engineering measures is disclosed. Other antigens which are produced by genetic engineering and which can be stably produced in a high yield in E.coli and subsequently purified therefrom are used as additional antigens for IgG detection. Finally, a set of antigens permits tests to be carried out to determine IgM antibodies against the virus. In addition, the components, produced by genetic engineering, of the surface proteins represent substances which can be used for prophylactic immunisation.
