To identify the presence of a particular virus, the dye is combined with antibodies known to attack that virus.

As these cells accumulate in the body, excessive quantities of an antibody known as IgM are produced.

Each clone of cells produces a single, pure antibody, known as a monoclonal antibody.

With new techniques, scientists have developed more specific antibodies, known as monoclonal antibodies, that can be directed against certain antigens in viruses.

The new antibody, known as L-6, selects as a target a variety of cancer cells.

Relatively simple blood tests can reveal whether the allergen-specific antibody known as IgE is produced in response to a given food.

PCD patients harbor an anti-neuronal antibody known as anti-Yo (named after the first two letters of the index patient).

Its name is derived from its binding specificity for a part of an antibody known as the Fc (Fragment, crystallizable) region.

A rapid, violent hyperacute response results due to preformed natural antibodies, known as XNAs.

The technique enabled the researchers to study the action of antibodies known to be involved in Graves' disease on the receptor protein.
