Antibody
An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to identify and neutralize pathogens such as bacteria and viruses. The antibody recognizes a unique molecule of the harmful agent, called an antigen, via the variable region. 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 blocking a part of a microbe that is essential for its invasion and survival). The ability of an antibody to communicate with the other components of the immune system is mediated via its Fc region (located at the base of the "Y"), which contains a conserved glycosylation site involved in these interactions. The production of antibodies is the main function of the humoral immune system.
Antibody (film)
Antibody is a 2002 science fiction thriller directed and edited by Christian McIntire that debuted as a Sci Fi Pictures TV-movie on the Sci Fi Channel on February 8, 2002.
A scientist (Lance Henriksen) leads a team in an experimental miniaturized craft injected into the bloodstream of a dying terrorist (Julian Vergov) whose body conceals a computer chip that will trigger a nuclear explosion in the U.S. Capitol Building in less than 24 hours.

You realize you're dead
Smiles upon your grave
A victim and a slave
Crawling beside yourself
Walking, no shadow
Did you hurt to heal?
Guess what; THIS PAIN IS REAL
YOU SUFFER
THIS PAIN IS REAL
Created people
Forced to feel the mark of death
To many living witness
Who lost their right to live
No flesh, no glory
Your greasy smile has disappeared
Did you die to feel
You'll see; THIS PAIN IS REAL
YOU SUFFER
THIS PAIN IS REAL
Did you hurt to heal
Did you die to feel
To see how's live in damnation
THIS PAIN IS REAL
Did you hurt to heal
Did you die to feel
To see how's live in damnation
Did you hurt to heal
