The antibody recognizes a unique part of the foreign target, called an antigen.

The monoclonal antibody recognizes the protein and locks onto it (like a key in a lock).

The monoclonal antibody recognizes specific proteins that are found on the surface of some lymphoma cells.

Two primary antibodies raised in different species recognize the target antigen or antigens of interest.

But the precision with which an antibody can recognize its shape complement is finite.

In contrast, most antibodies recognize a conformational epitope that has a specific three-dimensional shape and its protein structure.

But, if you are infected with a flu virus whose surface proteins have changed, your antibodies won't recognize them fully.

Prepared antibodies can recognize the resulting fragment, called a neoepitope, as a way to diagnose osteoporosis.

Each antibody recognizes a specific antigen unique to its target.

This antibody does not recognize uncleaved K18 and is therefore specific for apoptotic epithelial cells.
