This means that several secondary antibodies will bind to one primary antibody and enhance the signal.

For some of these, the area of the D-dimer to which the antibody binds is known.

Each antibody binds to a specific antigen by way of an interaction similar to the fit between a lock and a key.

An antibody binds its shape complement, key and lock.

About one antibody in a hundred thousand can bind a randomly chosen epitope.

The primary antibody seeks out and binds to the target antigen.

Overall, antibodies must bind to the antigens with a high specificity and affinity.

After that, if a person smokes, the antibodies would bind to the nicotine and prevent it from reaching the brain.

An antibody might bind that epitope and a family of similar shapes filling a ball in shape space.

The antibodies are free to float around the protein mixture and bind their targets.
