The five types of antigens are proteins, polysaccharides, lipids, nucleic acids, and glycoproteins. Proteins and polysaccharides are the most common types, often found on the surfaces of pathogens. Lipids and nucleic acids can also elicit immune responses, though they are less common as antigens. Glycoproteins are important in cell recognition and play a role in immune responses as well.
What else can I help you with?
Does anybody know what are the 4 blood types ?
Te four basic blood types are O, A, B and AB. They are named for the types of antigens they carry. O has no antigens, A has A antigens, B has B antigens and AB carries both.
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.
What types of antigens are recognized by B cells?
Processed fragments of protein antigens displayed on surfaces of body cells.
How are blood types different?
Blood types have different cells in them as well as different antigens.
Do Group O types have Antigens?
No, individuals with blood type O do not have A or B antigens on their red blood cells. This is why they are considered universal donors, as their blood can be transfused to individuals with A, B, and AB blood types without causing a transfusion reaction.
Why is type O considered the "universal donor"?
A type A blood sample contains A antigens which will conflict with any sample that does not have A antigens (B, O). O contains no antigens and therefore is compatible with all blood types.
What are examples of four different blood types?
The 4 blood types are:A - type A blood has antigen A and antibody anti-BB - type B blood has antigen B and antibody anti-AAB - blood type AB has both antigens A and B and has no antibodiesO - Type O blood has no antigens but has both antibodies anti-A and anti-B
What are the blood types in terms of antigens and antibodies?
There are four main blood types: A, B, AB, and O. These blood types are determined by the presence or absence of A and B antigens on the surface of red blood cells. Antibodies in the plasma target the antigens not present on the individual's own red blood cells.
What types of blood can people who are O positive accept?
People with O blood can only accept O blood. this is because type O blood does not have any antigens. Types A, B, and AB blood have A or B antigens, or both, respectively. If a person receives blood with antigens their blood does not contain it will cause their blood to clot and they will die.
Blood types are determined by the presence of protein located on what?
Blood types are determined by the presence of specific proteins (antigens) located on the surface of red blood cells. These proteins include A, B, and Rh (D) antigens.
What are The blood proteins A and B?
The blood proteins A and B are antigens found on the surface of red blood cells that determine blood type. Individuals with blood type A have A antigens, while individuals with blood type B have B antigens. Blood type AB individuals have both A and B antigens.
Which of these determine a person's blood type and stimulate antibody formation?
Antigens determine a person's blood type. These antigens are present on the surface of red blood cells and stimulate the immune system to produce antibodies against incompatible blood types.
