  • Publication number: 20240094218
    Abstract: Provided herein are methods of generating hybridomas and related methods of producing antigen-specific antibodies. In exemplary embodiments, the method comprises (a) preparing an enriched population of IgG-positive (IgG+) memory B cells from cells obtained from secondary lymphoid organs of one or more immunized non-human animals, wherein (i) less than or about 10% of the enriched population are IgM-positive (IgM+) B cells and/or (ii) the ratio of the IgG+ memory B cell count to IgM+ B cell count of the enriched population is greater than about 0.5, optionally, greater than about 1 or greater than about 2, (b) bulk-culturing the enriched population to obtain an expanded population; and (c) fusing cells of the expanded population with myeloma cells to obtain hybridomas. In exemplary aspects, the hybridomas obtained represent at least 10% or at least 15% of the IgG+ memory B cell repertoire produced by the immunized animals.

  • Publication number: 20230314417
    Abstract: The present invention relates to monoclonal antibodies that specifically bind to chemically-modified nucleic acid molecules, including pan-specific antibodies that bind to chemically-modified nucleic acid molecules independent of nucleotide sequence. The invention also relates to methods of generating monoclonal antibodies to chemically-modified nucleic acid molecules as well as methods of using such antibodies to detect nucleic acid molecules in biological samples. Various immunoassays incorporating the monoclonal antibodies of the invention are also disclosed.

  • Patent number: 11505614
    Abstract: The present invention relates to antibodies that bind to soluble BCMA (sBCMA). Moreover, the invention relates to a detection system comprising such antibodies. The antibodies or the detection system may be used for detecting or quantifying sBCMA, for diagnosing a disease associated with sBCMA, for patient stratification, monitoring disease progression, and evaluating the therapeutic response.

  • Publication number: 20220281966
    Abstract: The present invention is related to antibodies directed to IL-13 and uses of such antibodies. For example, in accordance with the present invention, there are provided human monoclonal antibodies directed to IL-13. Isolated polynucleotide sequences encoding, and amino acid sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions (FR's) and/or complementarity determining regions (CDR's), are provided. Additionally, methods of using these antibodies to treat patients are also provided.
