What blood has antigen but without antibody?
Surface antigen
What antigens and antibodies are in O- blood type?
there are no antigen in O blood and both A and B antigen in O blood.
If the anti-A antibody causes blood to coagulate which antigen would be present on the red blood cells?
a
What is the medical term for no antigen blood?
Red blood cells with an antigen on their surface are said to be Rh positive, Rh+. Rh negative, or Rh-, do nothave the surface antigen.
Sperm is not antigen why?
The reason why sperm is not an antigen is because it does not stimulate antibody production. An antigen typically occurs in blood plasma.
What does the presence of the Rh antigen mean?
Rh antigen, which is also called D antigen, indicates if the blood type is positive or negative. The presence of this antigen indicates the patient is Rh positive, the absence of this antigen reflects a blood type of Rh Negative. For example, if a person is O Positive, the Rh antigen is present.
What is the basic principle of blood transfusion?
Blood type A have antigen A and anti- body B Blood type B have antigen B and anti- body A Blood type AB have antigens A and B and no anti- body Blood type O do not have antigen but have anti- bodies A and B
Hemagglutination-inhibition test description?
It is the measures of the ability of soluble antigen to inhibit the agglutination of antigen-coated red blood cells by antibodies. In this test, a fixed amount of antibodies to the antigen in question is mixed with a fixed amount of red blood cells coated with the antigen (research on passive hemagglutination). Also included in the mixture are different amounts of the sample to be analyzed for the presence of the antigen. If the sample contains the antigen, the soluble antigen will compete with the antigen coated on the red blood cells for binding to the antibodies, thereby inhibiting the agglutination of the red blood cells.
What is RH typing?
Rh is an antigen. If you have the antigen, your blood type is A+, B+, AB+, or O+. If you don't have the antigen, your blood type is A-, B-, AB-, or O-. People WITH the Rh antigen, can receive from/give to people with Rh+ or Rh-. People WITHOUT the Rh antigen, can ONLY receive from/give to people with Rh- blood. (meaning people without the antigen) If Rh- and Rh+ blood comes in contact, the Rh- will produce antibodies towards Rh+, and at the second contact with the blood, will cause agglutination.
What is the carcinoembryonic antigen test?
The carcinoembryonic antigen (CEA) test is a laboratory blood study.
What is the explanation for the four main types of blood?
blood type A have antigen A and anti body B blood type B have antigen B and anti body A blood type AB have antigens A and B and do not have anti body blood type O do not have antigen but have anti bodies A and B
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.
