Abstract: The present invention relates to a method for the detection in body fluids of antibodies to hepatitis C virus (HCV), also known as a non-A non-B hepatitis (NANBH) virus and to the diagnosis of NANBH by the use of a composition of synthetic peptides. Each of these peptides has an amino acid sequence corresponding to immunodominant regions of a fusion protein and a non-structural polypeptide of HCV, SOD/HCV C100 and a postulated HCV structural (core) protein. More specifically, the present invention is directed to the use of a group of synthetic peptides in a prescribed sequence or their analogues for the detection of antibodies to HCV in body fluids. The detection method includes an enzyme-linked immunosorbent assay (ELISA), and other forms of immunoassay procedures.

Abstract: Erythropoietin (EPO) peptides and the use thereof for preparing epitope-specific anti-EPO antibodies are described. Also described are corresponding anti-EPO antibodies which take the form of polyclonal antibodies (antisera) or of monoclonal antibodies. These antibodies are suitable for purifying EPO, EPO derivatives or EPO peptides. The epitope-specific anti-EPO antibodies according to the invention can also be used for the detection of EPO and, in particular, for the epitope-specific detection of EPO. Additionally described are anti-idiotype antibodies which imitate a receptor region of EPO. Finally, pharmaceuticals which contain the said EPO peptides, anti-EPO antibodies or anti-idiotype antibodies, and diagnostic aids for the detection of EPO or of anti-EPO antibodies, are described.

Abstract: A novel arthropodicidally-active composition-of-matter is disclosed. Such a composition-of-matter comprises an aqueous lower alkanol solvent, and a toxicant as well as an emulsifier, both contained within the solvent. The amount of emulsifier, relative to the amount of solvent, is effective for forming a foam matrix that is able to collapse after a predetermined period of time thereby to form an arthropodicidally-active film. Also disclosed are methods for producing such an arthropodicidally-active film.
