Abstract: The present invention relates generally to the field of virology. More particularly, the invention relates to the discovery that peptides, which bind to the Hepatitis B virus (HBV) core and e antigens, can be used to inhibit HBV infection. Embodiments concern “binding partners”, which include peptides, peptidomimetics, and chemicals that resemble these molecules that interact with HBV core and e antigens, biological complexes having HBV core and e antigens joined to said binding partners, methods of identifying such binding partners, pharmaceuticals having binding partners, and methods of treatments and prevention of HBV infection.

Abstract: A composition, pharmaceutical composition, vaccine and method for the treatment of disseminated candidiasis due to the infection by C. albicans. The composition includes phosphomannan of C. albicans. Monoclonal antibodies for use in passive immunization against candidal infections.

Abstract: A homogeneous assay for determining the fumonisin content in grains uses the technique of fluorescence polarization. A grain extract is prepared by shaking a crushed grain sample with a solvent. A mixture is prepared by combining the grain extract with a tracer and with monoclonal antibodies specific to fumonisin. The tracer is able to bind to the monoclonal antibodies to produce a detectable change in fluorescence polarization. The tracer is prepared by conjugating fumonisin to a suitable fluorophore. The fluorescence polarization of the mixture is measured. The fumonisin concentration of the mixture may be calculated using a standard curve obtained by measuring the fluorescence polarization of a series of fumonisin solutions of known concentration.

Abstract: A method of stimulating an immune response in a human against malignant cells or an infectious agent comprises the step of administering to the human an immunogenic amount of a primate anti-idiotype antibody or antibody fragment that acts as an immunogenic functional mimic of an antigen produced by or associated with a malignant cell or an infectious agent. Sub-human primate anti-idiotype antisera, especially from baboons, are preferred. Such anti-idiotype antibodies are used to make vaccines for inducing preventive immunity or a therapeutic immune response against tumors, viruses, bacteria, rickettsia, mycoplasma, protozoa, fungi and multicellular parasites.

Abstract: High potency antibodies, including immunologically active fragments thereof, having high kinetic association rate constants and optional high affinities are disclosed, along with methods for producing such antibodies. The high potency antibodies disclosed herein are of either the neutralizing or non-neutralizing type and have specificity for antigens displayed by microorganisms, especially viruses, as well as antigenic sites present on cancer cells and on various types of toxins, and the products of toxins. Processes for producing high potency neutralizing antibodies and increasing the potency of already existing neutralizing antibodies are also described. Methods of using said antibodies in the prevention and/or treatment of diseases, especially diseases induced or caused by viruses, are disclosed.

Abstract: A composition, pharmaceutical composition, vaccine and method for the treatment of disseminated candidiasis due to infection by C. albicans. The composition includes phosphomannan of C. albicans, peptide mimotopes of phosphomannan epitopes, or polynucleotides encoding the peptide mimotopes. Monoclonal antibodies for use in passive immunization against candida infections are also provided.

Abstract: The invention relates to compounds which contain an antigen binding region which is bound to at least one enzyme which is able to metabolize a compound (prodrug) which has little or no cytotoxicity to a cytotoxic compound (drug), where the antigen binding region is composed of a single polypeptide chain. It is advantageous for covalently bonded carbohydrates to be present on the polypeptide chain.

Abstract: The subject of the invention is a new protein called EPIL or placentin, its analogs ing EPIL/placentin-type activity, obtained by deletion and/or substitution. The tion also concerns a DNA molecule coding for a EPIL/placentin-type polypeptide. It ly concerns a pharmaceutical composition containing EPIL/placentin or a /placentin analog.

Abstract: Therapeutic multispecific compounds comprised of anti-Fc&agr; receptor antibodies and methods of use are provided.
