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 disease.

2022年5月6日 · What do antibodies look like? Each antibody structure consists of two heavy chains and two light chains, which join to form a Y-shaped molecule. Each type of antibody …

2025年3月7日 · 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.

2023年8月3日 · They also modulate the antibody affinity to the FcR (s). The basic functional unit of an antibody is known as an immunoglobulin (Ig) which is monomeric, while the secreted antibodies can be dimeric or tetrameric or pentameric or polymeric. The antibody is made up of variable V regions, and constant C regions. Heterodimer structure of antibodies

2024年1月23日 · Antibody (Ab) also know as Immunoglobulin (Ig) is the large Y shaped protein produced by the body’s immune system when it detects harmful substances, called antigens like bacteria and viruses.

2 天之前 · 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.

2025年3月7日 · Antibody - Structure, Classes, Function: Each antibody molecule is essentially identical to the antigen receptor of the B cell that produced it. The basic structure of these proteins consists of two pairs of polypeptide chains (lengths of amino acids linked by peptide bonds) that form a flexible Y shape.

2024年7月23日 · An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (bacteria, fungi, parasites, and viruses)

2024年9月8日 · IgE: This antibody helps mediate allergic reactions in the body. IgE can bind to the surface of mast cells or basophils (types of white blood cells) and trigger hypersensitive …

Antibodies combine with specific antigens to generate an exclusive antibody-antigen complex. Learn about the nature of this bond and its use as a molecular tag for research.
