Antibodies are proteins normally found in our bodies that have the function of defending the body against foreign elements. They are also called immunoglobulins.

However, antibodies can also be synthesized in the laboratory, in such cases targeting other proteins involved in the development and progression of certain types of tumors. In such cases, antibodies have been classified in the class of molecularly targeted drugs. To learn more about molecular-targeted drugs, please see the Frequently Asked Questions – Molecular Targeting Drugs section.

Antibodies can also be used to identify cellular structures by immunohistochemistry.
