Astatine conjugated to an anti-CD20 monoclonal antibody eradicates disseminated B-cell lymphoma in a mouse model At-labeled 1F5 monoclonal antibody (mAb) (anti-CD20) was studied in both bulky lymphoma tumor xenograft and MRD Bifunctional decaborate (BNCS) reagent.
A non-cytotoxic antibody BK was rendered cytotoxic by coupling the antibody to the radioisotope astatine BK was chosen for this study since this antibody recognises an antigen which is uniformly distributed on human bone marrow leukocytes.
Hence the ability of astatine labelled antibodies. Astatine At anti-CD45 monoclonal antibody BC8-B10 binds to CD45 antigen, a receptor protein-tyrosine phosphatase expressed on the surface of both normal and malignant hematopoietic cells.
After binding and internalization by CDexpressing tumor cells, this agent may deliver a cytotoxic dose of alpha radiation.
Highly localized radiotherapy with radionuclides is a commonly used treatment modality for patients with unresectable solid tumors. Herein, we propose a novel α-nanobrachytherapy approach for selective therapy of human epidermal growth factor receptor 2 (HER2)-positive breast cancer.

To evaluate this hypothesis, ()At-labeled 1F5 monoclonal antibody (mAb) (anti-CD20) was studied in both bulky lymphoma tumor xenograft and MRD animal models.
Superior treatment responses to ()At-labeled. This is a list of therapeutic, diagnostic and preventive monoclonal antibodies, antibodies that are clones of a single parent used as drugs, the International Nonproprietary Names (INNs) end in -mab.
The remaining syllables of the INNs, as well as the column Source, are explained in Nomenclature of monoclonal antibodies. A monoclonal antibody (mAb or moAb) is an antibody made by cloning a unique white blood subsequent antibodies derived this way trace back to a unique parent cell.
Monoclonal antibodies can have monovalent affinity, binding only to the same epitope (the part of an antigen that is recognized by the antibody). In contrast, polyclonal antibodies.
