Each immunoglobulin class contains many different and unique antibodies.

There seemed to be more different antibodies than the total number of genes believed to exist in the human or animal body.

The test for the new virus requires a different antibody.

SR proteins were discovered independently through the use of two different monoclonal antibodies.

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

The plasma cells make a different antibody to fight each type of bacteria or virus that enters the body, to stop infection and disease.

This activity was inhibited when two different anti-alpha-toxin antibodies were introduced.

A human is born with about 100 million different antibodies, ready to meet an invasion.

Actually, humans generate about 10 billion different antibodies, each capable of binding a distinct antigen site.

Usually, the body's defense system generates a profusion of different antibodies to kill invading bacteria and viruses.
