How many types of antigens can bind to a single antibody?
An antibody can typically bind to one specific type of antigen.
Antibody binding result in destruction of the antigen?
Antibodies bind the antigen, which then targets the antigen for elimination by innate mechanisms
What is antigene and antibody?
An antigen is a substance that can invoke an immune response. While an antibody is the immune system's response to an antigen. Antibodies, act by directly neutralizing the antigen and/or bind to the antigen and signaling marcophages to phagocytose the antigen.
What is the relationship between antigen and antibody?
Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
What is antibody valence?
It is the number of antigens one antibody molecule can bind to. For example, a trivalent antibody can simultaneously bind to three copies of the antigen it recognizes. This is not related to atomic valence.
The y- shaped protein that is produced by plasma cells upon exposure to a specific antigen and can bind to that antigen is called a?
antibody
What function of this protein is to bind to a specific antigen preventing it from attacking host cells?
Antibody.
Are anitgens proteins?
Yes. An antigen is a substance that stimulates an animal in order to produce an antibody reaction to counteract the substance by a specific binding antibody-antigen. Most of the times this antigen is a molecule of protein.
What is the Role of a variable region of an antibody molecule?
Each antibody has a variable region at the top of the arms of the Y-Shaped structure of the antibody. These variable regions each have a different sequence of amino acids and therefore a different structure. This means that only specific antigens can bind to the binding sites - only those with a complementary shape. The antigen fits into the binding site by induced fit. Once the antigen has bound to the antibody it forms a highly specific antigen-antibody complex. Therefore the role of the variable region is to produce a specific binding site for each type of antigen.
What bind with specific antigens in the antigen-antibody response?
The Fab portion of the antibody is what determines the idiotype. The Fab portion consists of both a heavy and light chain and is connected to the Fc region (isotype). Every B cell will express a different Fab structure and in a single B cell it will produce only the same Fab.
Can any antibody work with any antigen?
No, not all antibodies can work with any antigen. Antibodies are highly specific in recognizing and binding to a particular antigen based on their unique binding sites. The binding of an antibody to an antigen is based on complementary shapes and charges, so a specific antibody will only bind to a specific antigen that matches its binding site.
What key features of the antibody recognizes the molecule that it binds to?
Anibodies are y-shaped bundles of proteins found throughout most mammalian bodies. The two prongs in the y shape are made out of an inner heavy chain and an outer light chain. The tips of the two prongs contain antigen binding sites that will react chemically to special chemicals called antigens on the cell membrane of a target cell. The antigen binding site of a specific antibody will only bind to a matching antigen, so numerous antibodies are needed to bind to all possible intruding organisms.
