"C antigen is an antigen in the Rhesus blood grouping system. This blood group system is associated with over 40 antigens which may or may not be present in a someone's blood, determining her or his place in this system. The most famous Rhesus antigen is the D antigen, sometimes called the Rhesus factor, which can cause complications in pregnancy. Blood analysis for C antigen can be performed in a lab which has the serotyping tools necessary to identify the presence of this antigen in the blood. As with some other antigens associated with blood types, the C antigen can create a blood incompatibility which may cause problems during pregnancy or with blood transfusions. If someone does not have this antigen and she or he is exposed to the blood of someone who does, C antibodieswill develop. With the next exposure, a coagulation reaction will occur in the blood. For this reason, it is important to avoid transfusing C positive blood into people who do not have the antigen.Whereas most blood types are determined by red cell antigens that differ by one or two amino acids, the Rh blood group contains the D antigen which differs from th"e C/c and E/e antigens by 35 amino acids. This large difference in amino acids is the reason why the Rh antigens are potent at stimulating an immune response

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
Which of the following is NOT true about antibodies a. an antibody has more than one antigen binding site b. a pathogen can have different epitopes c. a pathogen makes more than one antigen?
C is false.A pathogen can have multiple epitopes and antigens. A single antigen is simply one molecule, and the cell surface is littered with millions of antigens.
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.
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
What antigens are the most important in the Rhesus blood group system?
antigen D is the most important
Which portion of the antibody--V or C is its antigen--binding site?
C stands for constant or conserved, V stands for variable. The variable part is what latches on to the antigen.
Which of the following is NOT true about antibodies a. an antibody has more than one antigen binding site b. a pathogen can have different epitopes c. a pathogen makes more than one antigen?
C is false.A pathogen can have multiple epitopes and antigens. A single antigen is simply one molecule, and the cell surface is littered with millions of antigens.
What has the author M C Crowson written?
M. C. Crowson has written: 'Heterogeneity of antigen expression of colorectal tumours and their metastases'
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
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 is a C blood test?
You'll have to try to be more specific and provide some context. It could be a test for C-antigen on red blood cells, anti-C antibody, hepatitis C, protein C, C-reactive protein, or a number of other things.
What blood has antigen but without antibody?
Surface antigen
What is a monovalent antigen?
Another term for univalent antigen
