The invention provides an immunoassay kit providing an immunoassay kit comprising one or more analyte specific antibodies or fragments thereof, characterised that the antibody or fragment thereof comprises one or more non-disulphide cross-links between at least one heavy chain or fragment thereof and at least one light chain or fragment thereof of the analyte- specific antibodies or fragments thereof.

Methods and diagnostic compositions for detection of amyloid deposits using a chimeric (e.g., mouse-human) antibody or antigen-binding fragment thereof linked to a detectable label are disclosed.

Antibodies and meditopes that bind to the antibodies are provided, as well as complexes, compositions and combinations containing the meditopes and antibodies, and methods of producing, using, testing, and screening the same, including therapeutic and diagnostic methods and uses.

Provided herein are conjugated immunoglobulins and methods for generating conjugated immunoglobulins using a microbial transglutaminase.

Antibodies and meditopes that bind to the antibodies are provided, as well as complexes, compositions and combinations containing the meditopes and antibodies, and methods of producing, using, testing, and screening the same, including therapeutic and diagnostic methods and uses.

The present invention relates to therapeutic immunoconjugates comprising SN-38 attached to an antibody or antigen-binding antibody fragment. The antibody may bind to Trop-2 or CEACAM5 and the immunoconjugate may be administered at a dosage of between 4 mg/kg and 16 mg/kg, preferably 4, 6, 8, 9, 10, 12, or 16 mg/kg. When administered at specified dosages and schedules, the immunoconjugate can reduce solid tumors in size, reduce or eliminate metastases and is effective to treat cancers resistant to standard therapies, such as radiation therapy, chemotherapy or immunotherapy. Surprisingly, the immunoconjugate is effective to treat cancers that are refractory to or relapsed from irinotecan.

Novel chimeric and/or humanized forms of the anti-CD45 BC8 antibody are described. The disclosed chimeric or humanized antibodies can be used as research, diagnostic, or therapeutic tools against CD45-related disorders, such as hematologic malignancies including acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), other myeloid and lymphoid disorders, other cancers, as well as non-malignant disorders, such as autoimmune disorders, infections, inherited blood disorders, and metabolic disorders.

The present invention relates to an antibody or an antigen binding fragment thereof that specifically binds to L1-CAM (CD171), to a polynucleotide encoding at least one variable heavy chain sequence and/or at least one variable light chain sequence as in the antibody or an antigen binding fragment thereof of the present invention, to a host cell comprising the polynucleotide of the present invention, to an immunoconjugate comprising an antibody or an antigen-fragment binding thereof of the present invention and an active agent, to a pharmaceutical composition comprising the antibody or the antigen-binding fragment thereof of the present invention, or the immunoconjugate of the present invention, and their use in treatment and/or diagnosis. The antibodies, antigen-binding fragments thereof, the immunoconjugates and the pharmaceutical compositions described herein are particularly useful in treatment or diagnosis of an L1-CAM (CD171) associated cancer.
