Ways to tell them apart:
Antibodies are produced by the immune system, while antigens are substances that cause the immune system to produce these antibodies.
Antibodies help to identify and neutralize pathogens like bacteria and viruses, whereas antigens are the specific targets of these antibodies.
You can remember antibodies because they bind to antigens as their job, whereas antigens are the ones that trigger the immune response.
Antibodies circulate in the bloodstream, while antigens can be toxins, part of the pathogen, or any foreign particle.
Think of antibodies as the defense soldiers and antigens as the invaders or triggers for these soldiers.
