Antigens are protein substances formed in the blood to destroy foreign substances. Antigens can also be administered artificially in some cases.
No, type B blood does not have A antigens. Type B blood has B antigens.
Formed elements of blood do not include the defense proteins known as antigens. The formed elements of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Antibody is a protein made in response to a specific antigen. The antibody attaches to the antigen and makes it useless.
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.
Tissue Antigens was created in 1971.
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.
All cells produce antigens, or cell surface markers. The only question is whether the antigens are self antigens which means they belong in the body or they're foreign antigens which means they are an invading bacteria or virus (or a cancerous cell).
Examples of antigens are poisons, splinters and microorganisms.
