What is formed in the blood to fight invading antigens?
Antibody is a protein made in response to a specific antigen. The antibody attaches to the antigen and makes it useless.
An antibody reacts to what antigen?
An antibody reacts to the specific antigen it is made to attach to. It is like the lock and key model; it locks onto the antigen.
What is the protein made in a response to a specific antigen called?
An antigen is a protein made in response to a specific antigen.
What is an antigen made of?
An antigen may be made of either a bacteria or a virus. An antigen refers to a toxic or a foreign substance that once in the body attracts and is bound to a respective and specific antibody.
What are substances made in response to a specific antigen?
Giant turtles are what are made in response to a specific antigen. Hope I Helped!
An antibody can be treated to attach to a new antigen because the changes made to the?
variable region
What is a substance made in response to an antigen?
Antibodies
What are the 2 main parts of the immune system?
Primary versus Secondary Immune ResponseThe primary immune response occurs the first time that the immune system comes in contact with the antigen. During this time the immune system has to learn to recognize antigen and how to make antibody against it and eventually gain immunological memory. This primary response takes time (about two weeks) and during this time the person experiences signs of illness. IgM antibodies are the hallmark of a new infection because they are the first antibodies made when a person is exposed to an antigen for the first time. After the body learns to make IgM antibodies, it will start making IgG antibodies to the antigen.The secondary immune response occurs the second time (3rd, 4th, etc.) the person is exposed to the same antigen. At this point immunological memory has been established and the immune system can start making antibodies immediately. The antigen usually is killed within minutes and the person is not aware that he/she was attacked. The antibodies in this response are IgG and IgA or (in the case of allergy IgE).
What is the substance made by the body in response to stimulation by an antigen?
substance
What is the definition of antibody?
An antibody is a y shaped molecule which is specific to a particular antigen, it is a globular protein which is made by white blood cells called lymphocytes. These defend the body against antigens (alien cells).
Antigen and antibody?
An antigen is a foreign particle that enters the body. This could be a disease causing agent such as part of a bacterium or virus or could be a particle such as pollen or dust. An antibody is a protein made by the body's immune system. Antibodies react with specific antigens to enable the antigens to be removed from the body.
What does the Clonal Selection Theory state?
The Clonal Selection Theory explain how the immune system can be both diverse and very specific at the same time.The theory states:All antibodies are precommitted to making a single antibody with a single specificityA single cell produces only one antibody which interacts with only one antigen with the highest specificityWhen the right antigen interacts with that cell, it leads to clonal expansion and proliferation of that cell, so that many daughter-cells are made with the exact same specificityThe ability to recognise an antigen is dependent on a receptor, and the receptor is a product of the same cell that secretes the antibody. This ensures that made antibodies will fit with the antigen they are supposed to bind.A clone is defined as a group of cells in which all daughter cells are equal in their specificity
