Detailed explanation-1: -Antigens are any substance that the immune system can recognize and that can thus stimulate an immune response. (B lymphocytes) are white blood cells that produce antibodies specific to the antigen that stimulated their production.
Detailed explanation-2: -When the body senses foreign substances (called antigens), the immune system works to recognize the antigens and get rid of them. B lymphocytes are triggered to make antibodies (also called immunoglobulins). These proteins lock onto specific antigens.
Detailed explanation-3: -Anything that triggers an immune response is called an antigen. An antigen can be a microbe such as a virus, bacteria, toxins, chemicals or other substances that come from outside the body. If the body comes into contact with an antigen for the first time, it will store information about the germ and how to fight it.
Detailed explanation-4: -An antibody is a protein produced by the body’s immune system when it detects harmful substances, called antigens.
