Monoclonal Antibodies

What are Monoclonal Antibodies?

Monoclonal antibodies are specialized laboratory-produced proteins developed for binding to specific biological antigens or other molecular targets. Since they come from a single cell (or clone), they are especially consistent and accurate in the data they are involved in producing.

This type of antibody material has been shown to be a powerful tool in finding and subsequently destroying harmful cells in an organism, such as those found in cancers or various autoimmune diseases. This makes them excellent aids in medical testing and research, which is why they are so widely used.

AAA Biotech offers a comprehensive range of high-quality monoclonal antibodies that perform effectively in various laboratory tests, including (amongst others) ELISA, western blotting, immunohistochemistry, and flow cytometry. All of the products in our catalog are thoroughly quality tested to make sure that they are reliable and will consistently perform well in your research.

What Are The Uses of Monoclonal Antibodies

Monoclonal antibodies are used in many lab tests, including (amongst others) ELISA, western blotting, immunohistochemistry, and flow cytometry.

ELISA is a test that helps detect a specific substance/analyte in a sample. It uses antibodies (often monoclonal) bound to a solid surface (such as the well of a microplate) to “capture” the substance/analyte in the sample and immobilize it so that the detection antibody component can then bind to it and produce a signal, which can then be measured.

Western blotting identifies specific proteins in a sample. The sample is first separated on a gel, and then antibodies are applied that will typically bind to the target, which will all be localized to a single band in a lane.

Immunohistochemistry helps locate specific proteins in cells or tissue samples using antibodies.

Flow cytometry looks at and sorts cells. It uses antibodies that are conjugated to reporter molecules called “fluorophores”, which, under special lights, emit light themselves, which can then be measured by a detector instrument.

How Monoclonal Antibodies Are Used as Medicine?

Please note that all of the products listed in AAA Biotech’s also known as AAA Bio or AAABio catalog are strictly for research-use only (RUO).

Monoclonal antibodies can also be used as therapeutic/medical treatments, particularly in the context of cancers. They are designed to find and bind to specific cells or proteins, helping the immune system recognize and attack the cancer. These treatments work in different ways, such as:

• Radioimmunotherapy attaches a small amount of radioactive molecule to the antibody, so it delivers the radiation directly to the cancer cells that the antibody is specifically binding to.


• Antibody-directed enzyme prodrug therapy uses antibodies that are specifically bound to special enzymes. These enzymes activate a harmless drug in the body and turn it into a cancer-killing drug only near the cancer cells—this helps avoid harming healthy cells.


• Immunoliposomes are tiny “bubbles” filled with medicine/drug and coated with antibodies. They carry the drug straight to the cancer cells.
