Antigen A is the blood antigen which is present on the red blood cell surfaces of people who has blood types A and AB. Antigen B is the blood antigen which is present on the red blood cell surfaces of people who has blood types B and AB.

What is type A antigen?
Blood group A has A antigens on the red blood cells with anti-B antibodies in the plasma. The other common (and important) type of blood classification is the Rhesus or Rh blood group system. But not all blood is the same, and is classified into different types or groups.
What does an A antigen do?
An antigen is any substance that causes your immune system to produce antibodies against it. This means your immune system does not recognize the substance, and is trying to fight it off. An antigen may be a substance from the environment, such as chemicals, bacteria, viruses, or pollen.
What are 3 types of antigens?
There are different types of antigens on the basis of origin:
- Exogenous Antigens. Exogenous antigens are the external antigens that enter the body from outside, e.g. inhalation, injection, etc. ...
- Endogenous Antigens. ...
- Autoantigens. ...
- Tumour Antigens. ...
- Native Antigens. ...
- Immunogen. ...
- Hapten.
What is the healthiest blood type?
Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.
Is antigen good or bad?
Antigens are any substances that the immune system can recognize and that can thus stimulate an immune response. If antigens are perceived as dangerous (for example, if they can cause disease), they can stimulate an immune response in the body.
Is a virus an antigen?
“Antigens” are molecular structures on the surface of viruses that are recognized by the immune system and are capable of triggering an immune response (antibody production). On influenza viruses, the major antigens are found on the virus' surface proteins (see Figure 1).
Is it good to have antigens in your blood?
Antigens stimulate an immune response
Conversely, antigens that are found on the body's own cells are known as "self-antigens", and the immune system does not normally attack these. The membrane of each red blood cell contains millions of antigens that are ignored by the immune system.
What is a good antigen?
Characteristics of a good antigen include:
A minimal molecular weight of 8,000–10,000 Da, although haptens with molecular weights as low as 200 Da have been used in the presence of a carrier protein. The ability to be processed by the immune system.
What is the largest type of antigen?
The largest type of antigen is called a hapten.
What are antigens examples?
Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens.
