<p>Nucleoside thiotriphosphates carrying 32P in the gamma-thiophosphate group, prepared by reaction between a nucleoside diphosphate and a 32P labelled thiophosphate salt, are used as thiophosphorylating agents for antibodies that bind to tumour-associated antigens. The labelled thiotriphosphates can be used to introduce a therapeutically useful 32P atom into an antibody that has been modified by the incorporation into its structure of a peptide region capable of acting as a substrate for a phosphokinase. The resulting labelled antibody can then be used for injection in anti-tumour therapy and has clinical advantages over the corresponding phosphorylated analogue.</p> |
