How to Use Monoclonal Antibodies to Fight Cancer, Diabetes, and More

Monoclonal Antibodies
Human antibody (immunoglobulin)

Monoclonal antibodies are proteins produced by a single B-cell to bind to a target antigen specifically.

They were first discovered in 1975 by Japanese scientist Tasuku Honjo. The discovery of monoclonal antibodies has revolutionized the field of immunology and opened up new avenues for the treatment of diseases such as cancer, AIDS, and Alzheimer’s disease.

What are the Different Types of Monoclonal Antibodies?

Monoclonal antibodies (MAbs) are a type of protein created by the immune system to fight off foreign invaders. These proteins are made up of a unique combination of heavy and light chains, which makes them so effective for fighting off specific invaders.

There are three different types of MAbs:

Immunoglobulin G (IgG).

Immunoglobulin M (IgM).

Immunoglobulin A (IgA).

How do Monoclonal Antibodies Work?

Monoclonal antibodies are one of the most important discoveries in the history of medicine, and they are used to diagnose and treat many illnesses.

Monoclonal antibodies work by attaching themselves to a specific type of cell or molecule inside the body. Once they find their target, they release substances that kill them or stop them from acting on their prey. Monoclonal antibodies are made by fusing a copy of the immunoglobulin molecule from each of a person’s many B cells, which they create in the bone marrow, with an immortal cell line. Each fused B cell is called a hybridoma and can produce antibodies in response to an antigen exposed.

These antibodies are particular and can be collected from the blood, the spleen, or lymph nodes to detect the presence of an antigen. Monoclonal antibodies have a lower rate of side effects because they produce fewer antibody-antigen interactions than recombinant proteins or polyclonal antibodies.

How are Monoclonals Used in Medicine?

A monoclonal antibody is a type of protein made by the body or in a laboratory. They are used to treat many diseases, including cancer, arthritis, and asthma. Monoclonals work by finding specific targets on cells and binding with them, and this helps the immune system identify and destroy these cells.


The use of monoclonal antibodies in the medical field has significantly increased in the past few decades. This is because they are now used to identify and diagnose diseases and treat them, and they are also used to find cancer cells and monitor their development. Monoclonal antibodies are effective against various cancers, from lung cancer to melanoma.

The invention of monoclonal antibodies led to discovery that an overactive immune response caused many human diseases. This discovery led scientists on a path toward developing treatments for these diseases, such as rheumatoid arthritis and Crohn’s disease.
