ABSTRACT:
Nucleoside thiotriphosphates carrying .sup.32 P in the gamma-thiophosphate group, prepared by reaction between a nucleoside diphosphate and a .sup.32 P 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 .sup.32 P 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.
