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?
A antigen
Does o blood type have a antigens?
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.
Of the antigens in the rh group?
The most important Rh antigen is the D antigen.
What does an antigen do?
An antigen is a foreign body. It is used as a "template" to begin an appropriate immune response.
Can any antibody work with any antigen?

In order for a lymphocyte to respond to an antigen the antigen must?
the antigen must bind to the receptor
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 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 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 blood has antigen but without antibody?
Surface antigen
What is a monovalent antigen?
Another term for univalent antigen
Why the weak D antigen is known as Du antigen?
No.
Type blood has B antibodies?
