What is the purpose of monoclonal antibodies?
These are known as monoclonal antibodies (mAbs or Moabs). Monoclonal antibodies are used to treat many diseases, including some types of cancer. To make a monoclonal antibody, researchers first have to identify the right antigen to attack.
Why are m onoclonal antibodies used to treat cancer?
NOTE: Some m onoclonal antibodies used to treat cancer are referred to as targeted therapy because they have a specific target on a cancer cell that they aim to find, attach to, and attack.

What is the antibody that blocks HER2?
For example, trastuzumab (Herceptin) is an antibody against the HER2 protein. Breast and stomach cancer cells sometimes have large amounts of this protein on their surface. When HER2 is activated, it helps these cells grow. Trastuzumab binds to these proteins and stops them from becoming active.
Why do mAbs deliver radiation?
The drug and radiation are delivered directly to the target cells because the mAb looks for the target, then the radiation affects the target and nearby cells to a certain extent. Chemolabeled antibodies: These mAbs have powerful chemotherapy (or other) drugs attached to them. Examples include:
How are conjugated mAbs used?
These mAbs are used as a homing device to take one of these substances directly to the cancer cells. The mAb circulates throughout the body until it can find and hook onto the target antigen. It then delivers the toxic substance where it is needed most. This lessens the damage to normal cells in other parts of the body. Conjugated mAbs are also sometimes referred to as tagged, labeled, or loaded antibodies.
How do naked mAbs work?
(See Immune Checkpoint Inhibitors and Their Side Effects .) Other naked mAbs work mainly by attaching to and blocking antigens on cancer cells (or other nearby cells) that help cancer cells grow or spread.
