A protein made by plasma cells (a type of white blood cell) in response to an antigen (a substance that causes the body to make a specific immune response). Each antibody can bind to only one specific antigen. The purpose of this binding is to help destroy the antigen. Some antibodies destroy antigens directly. Others make it easier for white blood cells to destroy the antigen. An antibody is a type of immunoglobulin.
Definition of antibody
Examples of Antibodies
Examples of antigens include microorganisms such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produced when the immune system mistakenly considers healthy tissue a harmful substance.
Monoclonal antibodies (mAb or moAb) are antibodies that are made by identical immune cells that are all clones of a unique parent cell as opposed to polyclonal antibodies bind to multiple epitopes and are usually made by several different plasma cell (antibody secreting immune cell) lineages. MAB's are a type of protein made in the laboratory that can bind to substances in the body, including cancer cells. There are many kinds of monoclonal antibodies.
This is called an autoimmune disorder. Each type of antibody is unique and defends the body against one specific type of antigen.
