In one aspect, methods of generating human monoclonal antibodies that specifically binds to an allergen are provided. In some embodiments, the monoclonal antibodies are generated from sequences identified from isolated single B cells from a human subject who is allergic to the allergen.

The invention belongs to the field of biotechnology, in particular, relates to peptide fragment, monoclonal antibody, colloidal gold test strip and detection method thereof used for detection of stichopus oligopeptide. Sequences of the peptide fragments are KIVPGVPD and GRDGDQGPV. After identification, the peptides KIVPGVPD and GRDGDQGPV are newly discovered oligopeptides, which are exclusive peptide fragments of Stichopus oligopeptide.

The invention provides anti-Ara h 2 antibodies (e.g., an anti-Ara h 2 neutralizing antibody) and methods of using the same, e.g., for treating and/or preventing peanut allergy or sensitivity. Also provided herein are anti-Ara h 2 antibodies and methods of using the same, e.g., for diagnostics and methods of monitoring peanut oral immunotherapy.

The present invention relates to chimeric antibody receptors with anti-cotinine antibodies linked, and use thereof. A T cell presenting the chimeric antibody receptor on the surface secretes interferon gamma specifically for a target molecule of a cotinine-conjugated binding molecule that is added together therewith and induces cell death of the cell expressing the target molecule by the T cell. On the contrary, by administering a cytotoxic agent conjugated with cotinine, cell death of the chimeric antigen receptor T cell is induced. Therefore, if necessary, a cytotoxic agent conjugated with cotinine can be administered to remove the chimeric antigen receptor T cells that have been already administered, thereby suppressing immune side effects due to hyperactivity of T cells. Thus, the chimeric antigen receptor to which the anti-cotinine antibody is linked can be effectively and safely used for the treatment of cancer.

Methods and system for protein characterization using online chromatography and electrospray ionization mass spectrometry are provided.

The invention provides methods and compositions for treating allergies that use antibodies or other products of the immune system from whom have already experienced and responded to an allergen. In particular, people who have suffered from an allergic reaction to an allergen but subsequently become desensitized to the allergen produce immune products that may be isolated or reproduced for use in a therapeutic composition.

The current invention involves the use of protein lectins produced by plants including the non-toxic carbohydrate binding subunits (B subunits) of plant “AB toxins” (PTB lectins) as delivery vehicles for mobilizing associated drug substances for delivery to animal and human cells. The resulting protein fusions or conjugates retain lectin carbohydrate specificity for binding to cells and cellular trafficking activity so as to deliver an associated drug compound to the site of disease manifestation. One embodiment of this invention concerns the ability of ricin toxin B subunit, as a model PTB lectin, to deliver enzyme replacement therapeutic drugs to cells of several organs of the body including the brain and central nervous system, eyes, ears, lungs, bone, heart, kidney, liver, and spleen for treating lysosomal diseases.
