The antibodies bind to a protein found in blood clots.
Explain how monoclonal antibodies can be used to show the position of the blood clot.
Explain why the antibodies do not bind to the cells lining healthy blood vessels.
The marker attached to the antibodies is radioactive for only a few hours.
Suggest why.
