Immunoglobulin M (IgM) is the largest of several isotypes of antibodies (also known as immunoglobulin) that are produced by vertebrates.IgM is the first antibody to appear in the response to initial exposure to an antigen; [1] [2] causing it to also be called an acute phase antibody.
“The big difference with this test is the cost: It takes only 8 microliters of blood and 45 minutes to run the test at a cost of less than a penny per sample,” lead author Dr. Jose L. Montoya ...
An antibody–drug conjugate consists of 3 components: [31] [32] Antibody - targets the cancer cell surface and may also elicit a therapeutic response. Payload - elicits the desired therapeutic response. Linker - attaches the payload to the antibody and should be stable in circulation only releasing the payload at the desired target.
Passive antibody administration has become a widely approved cancer treatment following the development of monoclonal antibody (mAb). Since these antibodies originated from mice, they were wrought with problems of immunogenetics and poor abilities to induce an immune response in the human body, limiting their clinical applicability.

Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [2] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [3] and PARP inhibitors such as olaparib.

[4] [12] They provide an ideal means to characterize the T cells that respond to a vaccine, and they have been used to test T cell responses in many vaccine systems, including influenza, [13] yellow fever, [14] tuberculosis, [15] HIV/SIV [16] and a large number of cancer vaccine trials, [17] including melanoma and chronic myeloid leukemia. [18]
Examples include therapeutic cancer vaccines (also known as treatment vaccines, [14] which are designed to boost the body's immune system to fight cancer), CAR-T cells, and targeted antibody therapies. In contrast, passive immunotherapy does not directly target tumor cells, but enhances the ability of the immune system to attack cancer cells.
Main blood antibody of secondary responses, neutralize toxins, opsonization. All antibodies are Y shape, only some are dimer (sIgA) or pentamer (IgM). The Y-shaped structure has sites that effectively identify and bind pathogens. Able to suppress more than 99% of the antibody response against the bound antigen. [23] IgA Dimer 4 No 13% None
