In response to what it believes is an attack the mouse makes antibodies that latch onto the target molecule.

The term "gel" in this instance refers to the matrix used to contain, then separate the target molecules.

C4d is typically initiated by binding of antibodies to specific target molecules.

Therefore, the selection is done with mirrored target molecules.

This phosphorylation hinders the complex's ability to bind to certain target molecules.

One or more photons interact with the target molecule.

The task is harder than it might appear to those staring at the target molecule on the movie screen.

Or they can make billions of different antibodies using certain viruses in hopes one will bind to the target molecule.

This property allows the detection of low-level target molecules or rare events.

Monitoring this change over time allows to observe the binding behaviour of the target molecules.
