    摘要: Disclosed are immunogenic conjugates and therapeutic compositions that include such immunogenic conjugates. Also disclosed are methods of treating and/or inhibiting an Shigella sonnei infection. The disclosed immunogenic conjugates have the general structure: Pr—Sr—O—N═C-Kdo-OS wherein Pr is a carrier protein, Sr is an optional spacer moiety, Kdo is an 3-deoxy-D-manno-octulosonic acid or a derivative thereof, and OS is an oligosaccharide or polysaccharide obtained from S. sonnei. In specific examples, the immunogenic conjugates include the core oligosaccharide obtained from S. sonnei having the structure: wherein R is between 1 and 10 disaccharide repeat units. In specific examples, the disaccharide repeat unit included in the immunogenic conjugate has the structure: α-L-AltNAcA-3-β-FucNAc4N-4-.

    摘要: Methods for making an immunogenic conjugate that includes a hapten or an antigen covalently linked to a carrier. The methods include reacting a first agent with a dihydrazide resulting in a hydrazine-modified first agent, wherein the first agent is a hapten, an antigen or a carrier; reacting a second agent with a benzaldehyde compound resulting in a benzaldehyde-modified second agent, wherein the second agent is a hapten, an antigen or a carrier, provided that the first agent or the second agent is a carrier; and reacting the hydrazine-modified first agent with the benzaldehyde-modified second agent resulting in an immunogenic conjugate comprising a hapten or an antigen covalently linked to a carrier via a hydrazone linkage.

    摘要: The invention relates to improved methods of producing and recovering B. anthracis protective antigen (PA), especially modified PA which is protease resistant, and to methods of using of these PAs or nucleic acids encoding these PAs for eliciting an immunogenic response in humans, including responses which provide protection against, or reduce the severity of, B. anthracis bacterial infections and which are useful to prevent and/or treat illnesses caused by B. anthracis, such as inhalation anthrax, cutaneous anthrax and gastrointestinal anthrax.
