What else can I help you with?
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?
The O antigen is not an antigen that may be found on the surface of an erythrocyte. A and B antigens are present in the ABO blood group system, while the Rh antigen is part of the Rh blood group system. O blood type individuals lack A and B antigens on their red blood cells.
What blood has antigen but without antibody?
Surface antigen
What is a poliomyelitis antigen?
Poliomyelitis antigen is a complex compound on the surface of the virus.
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.
Blocking the antigen receptors on the surface of the lyphovytes would interfere with what?
destroying the antigen
Blocking the antigen receptors on the surface of the lymphocytes would interfere with what?
Antigen recognition
In biology what are blood types.?
Blood type has to do with the antigens found on the surface of your red blood cells. Type A has the A antigen, type B has the B antigen, type AB has both, and type O has neither.
What is rh protein?
Rh protein is an antigen found on the surface of red blood cells. It is responsible for the "positive" or "negative" portion of blood type designations.
What antibodies are tested for by Selectogen I and II?
Selectogen I tests for IgG antibodies to hepatitis A virus, hepatitis B virus core antigen, and hepatitis B surface antigen. Selectogen II tests for IgG antibodies to hepatitis C virus, hepatitis B core antigen, and hepatitis B surface antigen.
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.
Is a CD4 molecule also a type of antigen?
No, a CD4 molecule is not an antigen. CD4 is a protein found on the surface of helper T cells, a type of immune cell that plays a crucial role in the adaptive immune response by helping to coordinate immune responses. Antigens are molecules that can be recognized by the immune system, such as proteins on the surface of pathogens or foreign substances.
What is the difference between hepatitis B surface and hepatitis b antigen?
When your body is introduced to the Hepatitis B virus, the virus is considered the antigen (the surface antigen)and this should trigger your immune system to develop antibody against this antigen to destroy it. Most people do develop Hep B surface antibody when infected with the Hep B virus. Some people do not develop the antibodyand go on to have only circulating Hep B surface antigen - which means they are a carrier and can continue to have the virus and infection. For the majority of the population that develop the Hep B surface antibody, this conveys immunity to the virus for life.
