摘要:
A gene of varicella-zoster virus (VZV) which encodes immunogenic outer surface viral proteins has been identified by DNA sequence analysis. Antibodies directed against peptides imputed from the DNA sequence can react with the glycoprotein, which itself is reactive with neutralizing antibodies. The amino-terminal sequence of the purified glycoprotein is identical to a portion of the amino acid sequence imputed from the DNA sequence. This glycoprotein is useful for the preparation of a vaccine against VZV.

摘要:
A gene of varicella-zoster virus (VZV) which encodes immunogenic outer surface viral proteins has been identified by DNA sequence analysis. This gene can hybrid select messenger RNA which encodes and expresses a protein which reacts with human convalescent zoster sera and with polyclonal monospecific antisera which neutralize viral infectivity. These proteins are useful for the preparation of a vaccine for VZV.

摘要:
A gene of varicella-zoster virus (VZV) which encodes immunogenic outer surface viral proteins has been identified through DNA sequence analysis. Fragments of the DNA have been cloned into a vector which, when placed into a host organism, expresses proteins which react with human convalescent zoster sera and with monoclonal antibodies which neutralize viral infectivity. These proteins are useful for preparation of a vaccine for VZV.
摘要:
A high molecular weight polysaccharide intracellular adhesin (SAE) antigen having the general structure of poly-1,6,β-2-amidoglucopyranoside, which is variable substituted with N-acetyl and O-succinyl substituents is described. Also, a method is given for isolating this antigen from Staphylococcus aureus. The SAE can be used in a vaccine, either alone, conjugated to an immunogenic protein, and/or with an immunogenic adjuvant.
摘要:
A process of purifying target molecules is described that involves the selection of ligands based on identifying, in real time, association and dissociation constants with a given target molecule; using this information to select at least one ligand that exhibit predetermined association and dissociation constants with a given target molecule; anchoring a quantity of ligand to an activated solid support; contacting a quantity of target molecules with the anchored ligand(s); removing low affinity target molecules from anchored ligand and eluting particularly pure target molecules.
摘要:
Immunological conjugates of HIV-specific selected principal neutralization epitopes are prepared. These epitopes bind 19b, a broadly neutralizing human monoclonal antibody specific for the HIV gp120. The epitopes are identified from oligopeptide epitope libraries. The conjugates are useful for vaccination against AIDS or ARC, as well as in the production of other HIV-specific broadly neutralizing antibodies for passive immunity against AIDS or ARC.
摘要:
The invention provides compositions and methods for the treatment of diseases associated with amyloid deposits of Aβ in the brain of a patient, such as Alzheimer's disease. Such methods entail administering an immunogenic fragment of Aβ, lacking a T-cell epitope, capable of inducing a beneficial immune response in the form of antibodies to Aβ. In another aspect, the immunogenic fragment of Aβ is capable of elevating plasma Aβ levels. The immunogenic fragments comprise linear or multivalent peptides of Aβ. Pharmaceutical compositions comprise the immunogenic fragment chemically linked to a carrier molecule which may be administered with an adjuvant.
摘要:
A protein which inhibits collagen-stimulated platelet aggregation. The protein has a molecular weight of approximately 17,000. A method of isolating the protein from Ornithodoros moubata and using the protein to prevent or delay blood coagulation by blocking the stimulation of platelet aggregation by collagen is also described. The protein is useful in the prevention, prophylaxis, therapy and treatment of thrombotic diseases.
