Hers your answer buddy...

An antibody (Ab), also known as an immunoglobulin (Ig) is a large Y-shaped Protein

Each tip of the "Y" of an antibody contains a paratope(analogous to a lock) that is specific for one particular epitope (similarly, analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly (for example, by inhibiting a part of a microbe that is essential for its invasion and survival).
