What is a substance usually a protein that causes the formation of an antibody and reacts specifically with that antibody?
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
A foreign molecule that causes a specific immune response is?
Depending on the exact response, the substance is generally called a pathogen, yet more specifically depending on the nature of the response and origin of the substance, could be an antigen, allergen, carcinogen, etc.
What is the carcinoembryonic antigen test?
The carcinoembryonic antigen (CEA) test is a blood test used to measure the level of a protein that may be elevated in certain types of cancer, particularly colorectal cancer. It is often used to monitor cancer progression, assess response to treatment, and detect cancer recurrence. However, it is not specific to cancer and can also be elevated in non-cancerous conditions.
What is the foreign protein that invades an organism?
Prions are the proteins which invades organisms.. they are usually proteinaceous material devoid of nucleic acid but yet capable of producing diseases in humans and other animals..examples are scrapie, kuru, etc..
When an antigen is bound to a class II MHC protein it can activate what cell?
When an antigen is bound to a class II MHC protein, it can activate helper T cells. Helper T cells play a critical role in initiating and coordinating immune responses by releasing various signaling molecules and activating other immune cells.
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 the medical term meaning a specific protein evoked by an antigen?
An antibody is a specific protein evoked by an antigen.
What is the specific protein made in response to a particular antigen?
The specific protein made in response to a particular antigen is called an 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.
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 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.
What function of this protein is to bind to a specific antigen preventing it from attacking host cells?
Antibody.
A screening test to detect prostate cancer that measures protein levels is called?
The prostate-specific antigen (PSA) test is a blood screen for prostate cancer.
What is a substance usually a protein that causes the formation of an antibody and reacts specifically with that antibody?
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
What is a specific term for a bacterial or other foreign protein that initiates antibody production by the body?
antigen
What are anti bodies and antigen?
The antigen is the foreign "invader" in the body. The antibody is a tiny "Y" shaped protein that is chemically attracted to a specific antigen; binding to it and thereby marking it for destruction by a white blood cell.
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).
