What else can I help you with?
Which of the following is not an antigen that may be found on the surface of an erythrocyte a A antigen b B antigen c O antigen d Rh antigen?
The O antigen is not an antigen that may be found on the surface of an erythrocyte. A and B antigens are present in the ABO blood group system, while the Rh antigen is part of the Rh blood group system. O blood type individuals lack A and B antigens on their red blood cells.
What is the process by which an antibody binds to an antigen?
The process by which an antibody binds to an antigen is called antigen-antibody binding. This occurs when the antibody recognizes and attaches to a specific part of the antigen, forming a complex that helps the immune system identify and neutralize the antigen.
Virus bacterium or toxins that the body regards as foreign is known as?
antigen
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 happens when an antigen and its matching antibody meet up in your body?
When an antigen and its matching antibody meet in the body, the antibody binds to the antigen, marking it for destruction by the immune system. This process helps to neutralize the antigen and prevent further harm to the body.
What are important tumor markers in the is antigen class?
alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), prostate specific antigen (PSA), cathespin-D, HER-2/neu, CA-125, CA-19-9, CA-15-3, nuclear matrix protein, and bladder tumor-associated antigen
What is the molecule that can be recognized by the immune system?
Antigens.
What is antigen in German?
Abwehrstoff or Antigen
In order for a lymphocyte to respond to an antigen the antigen must?
the antigen must bind to the receptor
Which of the following is not an antigen that may be found on the surface of an erythrocyte a A antigen b B antigen c O antigen d Rh antigen?
The O antigen is not an antigen that may be found on the surface of an erythrocyte. A and B antigens are present in the ABO blood group system, while the Rh antigen is part of the Rh blood group system. O blood type individuals lack A and B antigens on their red blood cells.
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 molecule is connected to the surface of pathogens?
An antigen is a molecule that is located on viruses, bacteria, cancer cells, and other pathogens. An antigen is very specific to each pathogen. A flu antigen is different from a pneumonia antigen, and an HIV antigen is different from a measles antigen. I like to think of an antigen as a lock, understanding that all locks are different and very specific. The key that fits these antigen locks is called an antibody. Antibodiesare found on certain types of white blood cells that our body produces. Antibody-producing white blood cells are called lymphocytes. Lymphocytes travel around our body and attach antibodies to pathogen antigens. Once an antigen has an antibody attached to it, phagocytes attack the pathogen, engulf it, and kill it. Sometimes the antibody disables the pathogen so that it cannot reproduce or release toxins.SourceBYU Course BIOL 049 Lesson 3
What are characteristics of adaptations?
1-Response is antigen-dependent 2-There is a lag time between exposure and maximal response 3-Antigen-specific 4-Exposure results in immunologic memory
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.
Type blood has B antibodies?
Has no antigen in many textbooks it will state "no A-antigen and no B-antigen"(which imply the possibility of some other antigen) and some will even say, "no antigen" (which is true; antigens are things that attach to antigen binding sites, thus, if it does not fit any antigen binding sites, it is technically not a antigen but merely a "enzyme/protein") but this is just to reduce unnecessary and irrelevant information; they are only concerned about A-antibody, B-antibody, A-antigen, and B-antigen. Nonetheless, know that there are in fact antigens on o blood cells, they are just inactive. My guess is, N acetyl glactosamine on A antigen and Galactose on B antigens are Epitopes (: a small specific regions on antigens that are bound by the antigen receptors on lymphocytes and by secreted antibodies.) Antigens without epitopes will not be detected by antigen binding sites.
Why the weak D antigen is known as Du antigen?
No.
What blood has antigen but without antibody?
Surface antigen
