Provided herein are methods for rational design of nicotine haptens. More particularly, provided herein are methods for designing, selecting, and synthesizing nicotine haptens and nicotine hapten conjugates. Also provided herein are novel nicotine haptens and methods for using nicotine haptens to treat nicotine addiction.

The present invention generally provides compositions methods and composition relating to the diagnosis and/or treatment of cancers having a cell surface de-N-acetylated sialic acid antigen, e.g., an at least partially de-N-acetylated ganglioside and/or a de-N-acetylated sialic acid-modified cell surface protein.

Disclosed herein are antibodies which specifically bind to at least one epitope defined by the immunogenic glycopeptide. Other aspects of the present disclosure are pharmaceutical composition comprising the antibody; and method for preventing and/or treating Globo-H-positive cancer.

Disclosed herein are antibodies which specifically bind to at least one epitope defined by the immunogenic glycopeptide. Other aspects of the present disclosure are pharmaceutical composition comprising the antibody; and method for preventing and/or treating Globo-H-positive cancer.

Disclosed is an isolated antibody or an antigen-binding fragment thereof The antibody is capable of binding to a muramyl peptide, or a derivative or an analog or a salt thereof. The muramyl peptide comprises muramic acid and an amino acid selected from the group consisting of alanine, isoglutamine, glutamic acid, and a salt thereof. Also disclosed are methods of producing the antibody, compositions comprising the antibody, methods of treating using the antibody, uses of the antibody, methods of detecting muramyl peptide, an assay for detecting muramyl peptide, an antibacterial agent, hybridomas and kits.

Provided herein are polypeptides comprising portions of the influenza virus hemagglutinin, compositions comprising such polypeptides that can be used as immunogens in vaccines and methods of their use to generate an immune response against multiple influenza subtypes in a subject.
