Antibody - Wikipedia
An antibody (Ab), or immunoglobulin (Ig), is a large protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as those that exist on bacteria and virus cells, including those that cause disease.

Antibody | Definition, Structure, Function, & Types | Britannica
Antibody, a protective protein produced by the immune system in response to the presence of a foreign substance, called an antigen. Antibodies recognize and latch onto antigens in order to remove them from the body. Learn more about the function and structure of antibodies in this article.

Antibody - National Human Genome Research Institute
An antibody is a protein component of the immune system that circulates in the blood, recognizes foreign substances like bacteria and viruses, and neutralizes them.

Monoclonal antibody - Wikipedia
Monoclonal antibody A general representation of the method used to produce monoclonal antibodies [1][2] A monoclonal antibody (mAb, more rarely called moAb[3]) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell.

What is an antibody? - Medical News Today
An antibody is a protein that develops in response to a foreign invader (the antigen). An antigen can be a protein, lipid, carbohydrate, or nucleic acid.

Antibody - Simple English Wikipedia, the free encyclopedia
The specific antibody that is produced to fight Group A streptococcus is called Antistreptolysin-O, also known as ASO. [13] Detection of ASO via antistreptolysin-O titer or anti-deoxyribonuclease B (anti-DNase B) is a common way of testing for a group A streptococcal infection. These tests indicate if streptolysin antibodies are present.

Antibodies - an overview | ScienceDirect Topics
Antibodies circulate around the body in the blood and fluids. The binding of an antibody to its target is often sufficient to render the antigen harmless. Toxins produced by some bacteria can be neutralized upon recognition by a specific antibody that will block its ability to bind to specific cellular targets. Similarly, antibodies to viral particles will impede their interaction with ...
