Antibody
Antibodies must be created for a specific antigen.
Antibody.
Antibodies bind the antigen, which then targets the antigen for elimination by innate mechanisms
produce antibodies Plasma cells are antibody-manufacturing cells derived from B lymphocytes, following their activation by an antigen. They are responsible for humoral immunity - immunity conferred by antibodies present in the blood plasma. Plasma cells are capable of synthesising and secreting antibodies at a rate of 2000 molecules per second. Each cell will only synthesise and secrete one type of antibody. This antibody will bind specifically to the antigen that initially activated the precursor B lymphocyte. Plasma cells will synthesise and secrete antibody molecules over their short life span of 4 to 5 days. The secreted antibodies circulate in the blood or lymph and bind to their complementary antigen, thus marking them for destruction by other mechanisms.
Vaccination introduces foreign antigen and the body responds by producing antibodies for that specific antigen. So overall levels of antibody may not considerably increase, but antibodies specific for that antigen will increase dramatically.
An antigen is a substance that can invoke an immune response. While an antibody is the immune system's response to an antigen. Antibodies, act by directly neutralizing the antigen and/or bind to the antigen and signaling marcophages to phagocytose the antigen.
Epitope, it is the part of the antigen that is recognized and binds by the antibodies.
An antigen are the germs that enter the body, and antibodies are the thing that the body produces to kill them.
Type AB blood doed not contain any antibodies. I does have Antigens A and B.
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
Antibodies are basically all the same except for a tip that recognizes the corresponding antigen. When the antibody finds this antigen it locks on and targets the virus.
