Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause ...
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.
An antibody is a protein produced by your immune system to attack and fight off these antigens. How do antibodies fight off antigens? The molecules on the surfaces of antigens differ from those found naturally in your body.
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. Antibodies are an essential component...
Antibody (Immunoglobulin) diversity. The immune system has the ability to generate a high level of diversity in order to recognize a very vast range of unique molecules estimated to be in billions. With this capability, foreign structural, foreign antigens can be recognized and eliminated.
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.
Follow NCBI. Antibodies are naturally produced by plasma cells within the human body to mediate an adaptive immune response against invading pathogens. There are five predominant antibodies produced, each specialized to execute certain functions.
