The applicability of mouse monoclonal antibody MOC-31 for in vivo radioimmunodetection of human small cell lung cancer (SCLC) was investigated in a nude rat xenograft model. MOC-31 is reactive with a 38 kD pancarcinoma membrane antigen. [111In]DTPA-MOC-31 showed good in vivo immunolocalisation to xenografted SCLC cells, whereas antigen-related uptake was low in normal rat tissues and in a control antigen-negative, human-derived tumour. Non-antigen-related uptake in the liver could be blocked by pretreatment with irrelevant antibody. It is concluded that MOC-31 can be used for radioimmunodetection of SCLC in vivo and may be suitable as a targeting device in patients.
