How many types of antigens on the erythrocytes?

There are two main types of antigens on erythrocytes - ABO antigens and Rh antigens. ABO antigens include A and B antigens while Rh antigens include RhD antigen. These antigens play a crucial role in determining blood type compatibility for blood transfusions.


Does O blood have any antigens present?

No, O blood does not have any antigens present.


What are the A B AB and O blood groups distinguished by?

The ABO blood group system classifies blood based on the presence or absence of certain antigens on the surface of red blood cells. Type A blood has A antigens, type B blood has B antigens, type AB blood has both A and B antigens, and type O blood has neither A nor B antigens.


Do antibodies attack extracellular or intracellular antigens?

Antibodies primarily target extracellular antigens, which are found outside of cells. These antigens can be on the surface of pathogens or released into the extracellular environment. Intracellular antigens, located inside cells, are primarily targeted by T cells of the immune system.


Glycoproteins that react specifically with the chemical structures in the antigen that induced them are called what?

Glycoproteins that react specifically with the chemical structures in the antigen that induced them are called antibodies. Antibodies are produced by the immune system in response to the presence of antigens, and they bind to these specific structures to neutralize or mark them for destruction by other immune cells.

How do antibodies react to antigens?

Type B antibodies react to type B antigens by begining to clump together, and the clumps may block blood vessels.


What happens if Coombs' tests are positive?

If the test is positive, the antigens that react will narrow the search for a cause


When antibodies bind antigens the clumping of antigens result from?

There are four reactions when antibodies react with antigens: agglutination, precipitation, neutralization or activation of complement. Agglutination is the clumping process that you are looking for.


Serological testing is based on the fact that antibodies react specifically with an anigen all bacteria have the same antigens or the human body makes antibodies against bacteria?

AnswerThe human body makes specific antibodies to specific antigens (ex. proteins on a bacterial membrane) that it encounters. Bacteria do not all have the same antigens.* antibodies react specifically with an antigen


What are antigens determining blood type carried on?

Antigens, by definition, cause the body to produce antibodies which act against them. You inherit certain antigens which are on your red blood cells. Sometimes these antigens are absent from your RBC. If you are type B, you have B antigens. Type A has A antigens, AB has AB antigens and type O has no antigens. If you are type AB, you can receive AB blood from some one else.


What type of marker is on type b blood?

Type B blood has B antigens on the surface of its red blood cells. In addition to these B antigens, type B blood also contains A antibodies in the plasma, which can react against A antigens found in type A blood. This combination of antigens and antibodies is crucial for blood transfusions and compatibility.


What protein inactivates viruses?

Iron and fiber.


What is h and o antigens?

H antigens correspond to the antigenic type of the bacterial flagellaO antigens correspond to the antigenic type of the Lipopolysaccharide layer on the outer membrane of gram negative bacteriabacteria all have different antigenic types on their surface which react to different types of antibodies and are classified using this method. For example the pathogenic E. coli O157:H7 has the designation 157 for its O antigen meaning it will not react with antibodies with a different serotype.


What is an antirepressor?

An antirepressor is an enzyme which blocks or inactivates a repressor.


If an individual is transfused with the wrong type blood the recipients antibodies react with the donors antigens eventually clumping and hemolyzing the donated RBC?

true


What kind of anigen does type o blood have?

Type O blood does not have any antigens. This is the reason for O blood's universal donnor status. Since no antigens (proteins or polysaccharides) are present, they will no react negatively to any antibodies that other blood types possess.


Does Type B blood have A antigens?

No, type B blood does not have A antigens. Type B blood has B antigens.
