A monoclonal antibody is an antibody (a type of protein) that has been designed to recognise and bind to a specific structure (called an antigen) that is found in certain cells in the body.
Monoklonaalne antikeha on selline antikeha (teatud tüüpi valk), mis tunneb ära teatud keharakkudes esinevat spetsiifilise struktuuri (mida nimetatakse antigeeniks) ja seondub sellega.
