Human beings (and all jawed vertebrates) possess the ability to make antibodies ready to
acknowledge (by binding to) practically any antigenic determinant (epitope)
to discriminate amongst even very similar epitopes.
Not just does this offer the premise for defense in opposition to sickness organisms, but it surely tends to make antibodies interesting candidates to target other types of molecules found during the body, such as:
receptors or other proteins current around the surface of usual cells
molecules current uniquely within the surface of cancer cells.
Therefore the exceptional specificity of antibodies would make them promising agents for human remedy. Picture, for instance, being capable to
make an antibody that should bind only towards the most cancers cells in a client
coupling a cytotoxic agent (e.g. a powerful radioactive isotope) to that antibody, after which
offering the sophisticated into the individual so it could find out and demolish the cancer cells (and no normal cells).
