In a previous study, hMN-14 labeled with Indium-111 (111In) and conjugated to IRDye800CW ([111In]In-DTPA-hMN-14-IRDye800CW) was shown to specifically accumulate in CEA-expressing tumor xenografts and enabled radio- and fluorescence-guided surgery of colorectal tumor nodules [7]. This evidence concerns the gene CEACAM5 and neoplasm.
