The present disclosure relates generally to immunoglobulin-related compositions (e.g., antibodies or antigen binding fragments thereof) that can bind to the CDS 3 protein. The antibodies of the present technology are useful in methods for detecting and treating Alzheimer's disease or a CD33-associated cancer in a subject in need thereof.

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

The present disclosure provides compositions and methods for the treatment of cancer. Specifically, the compositions of the present technology include novel clearing agents that may be used in pretargeted radioimmunotherapy.

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

The disclosure provides radiolabeled and/or cytotoxin labelled antibodies and methods and uses of these antibodies. In one embodiment, provided is a cytotoxic agent comprising an antibody that specifically binds a target disease cell surface receptor, a cytotoxin, and a radiolabel, wherein the cytotoxin is linked directly or indirectly to the antibody, and wherein the radiolabel comprises a radionuclide and optionally a scaffold, wherein the scaffold is directly or indirectly coupled to the antibody. Also provided are methods of preparing the cytotoxic agent and methods of treating disease using the cytotoxic agent.

The present disclosure provides compositions and methods for improved pre-targeted radioimmunotherapeutics (PRIT) to treat various hematological disorders, such as B cell hyperproliferative disorders and solid tumors. The disclosed compositions include bispecific antibody compositions having a first domain that specifically bind to an antigen such as CD38, BCMA, Muc1, GPRC5D, or Slam7 and a second domain that specifically binds to a radioactive ligand. Methods include administering the disclosed bispecific antibody reagent and separately administering the radioactive ligand. In some embodiments, a clearing agent is also administered. In some embodiments, the therapeutic methods comprise administering a combination of two or more bispecific antibody reagents. In some embodiments, an enhancing agent, such as ATRA, gamma secretase inhibitor, or dextramethasone, is also administered to enhance expression of the target antigen on the target cells.

The present disclosure relates generally to immunoglobulin-related compositions (e.g., antibodies or antigen binding fragments thereof) that can bind to and neutralize the activity of A33 protein. The antibodies of the present technology are useful in methods for detecting and treating an A33-positive cancer in a subject in need thereof.

The present invention relates to compositions and methods employing conjugates that include a self-assembly and disassembly (SADA) polypeptide and a binding domain. The present invention encompasses the recognition that conjugates with a SADA polypeptide have certain improved biological properties. SADA-conjugates are described, along with uses thereof (e.g., as therapeutic or diagnostic agents) and methods of manufacture.

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

The disclosure provides radiolabeled and/or cytotoxin labelled antibodies and methods and uses of these antibodies.
