The aim of this work is to provide an accurate and scientific method of radionuclide imaging for small cell lung cancer with Tcm-2F7 F (99ab′ ) 2 . The monoclonal antibody 2F7 F (ab′ ) 2 segment was derived by iminothiolane and ligand exchange from Tcm O ( GH ) 99? 2 . Labeling efficiency was measured by paper chromatography. The label- ing efficiency of the labeled antibody 2F7 F ( ab′ ) 2 was 93.5%
with 2.5% colloidal Tcm in it. The competition test in 99 vitro showed that Tcm bound with the high affinity sites of antibody. The stability of the iminothiolane modified 99 antibody 2F7 F ( ab′ ) 2 could be kept at 4℃ for 3 months. In conclusions
the labelling method applied to the preparation of 99Tcm labeled antibody 2F7 F ( ab′ ) 2is successful
and appears to be equally applicable to other antibodies.
