Antibodies are usually made in response to being exposed to an antigen. If you have had measles, then you have made antibodies to that antigen. Next time you are exposed, your body will fire up the antibodies and you will defeat the antigen (measles) quickly. You may feel some thing. You might say "I am coming down with something" but it will pass quickly.
In RBC, the genetic make up of the blood gives antibodies for each type. These are already in the plasma. There are antigens on each type of RBC.
1. Type A blood has antigen A on it's surface while antibody B is in the plasma. This person can be given A and a bad reaction will not occur as there is no antibody A in the plasma.
2. Type B has antigen B and antibody A in the plasma. Type B blood can be given but not A.
3. Type O has both antigens A and B and no antibodies for A or B. Only O can be given.
4. Type AB has no antigens on it's surface and both antibodies A and B. Types O, B, A, and AB can be given.
It is always desirable to give the same blood type. However, if it is very necessary, O can be given to all other blood types. It is called the universal donor.
AB can take any other blood type and is called the universal recipient.
To further complicate things RBCs also have an Rh factor and are called Rh+.
If not they do not, they are Rh-. These also should match. However O- is the actual universal donor.

The body's usual response to detection of antigens is to synthesize?
antibodies
What is the difference between antibodies and antigens?
Antigen is a substance that can induce the generation of antibodies, any substance that can induce immune response. Antibody is a protective protein produced by the body in response to an antigen.
How are antigens associated with antibodies?
Antibodies are produced in response to antigens. If you get infected with one of the 200 viruses that cause colds, these viruses are antigens and your body will respond by making antibodies. The antibodies will inactivate the virus. It usually takes 7-10 for the process to be complete.
What is the immune response that produces antibodies to kill pathogens and recognize them in the future?
Antigens
What is the role of antigens in the immune response to chickenpox?
The antigens cause an immune response leading to production of antibodies thereby causing the host to be resistant to subsequent infection
What is involved in bloody typing and screening?
Blood typing and screening tests are based on the reaction between antigens and antibodies. An antigen can be anything that triggers the body's immune response.
What happens once the body has been expose to a pathogen?
This type of reponse is the adaptive response which develops over the life span and "learns" and "remembers". This makes antibodies in response to antigens.
What class of macromolecule would antibodies belong?
Antibodies belong to the class of macromolecules known as proteins. They are Y-shaped proteins produced by the immune system in response to the presence of foreign substances called antigens.
What are antigens and antibodies?
antigen-a toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.Antibodies-a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
In order for antigens to incite the immune response they must be?
in order for antigens to incite the immune response the y must be ?
When a foreign substance invades the body what is it called?
Antigenan·ti·gen/ˈantijən/Noun:A toxin or other foreign substance that induces an immune response in the body, esp. the production of antibodies.
Are antigens produced by white blood cells and attack substances that may be harmful to the body?
Antigens are foreign proteins that your immune system can recognize as being harmful to your body, so it produces antibodies that memorize the antigen protein so it can launch an immune response if it ever again invades your body.
