Technetium (99mTc) votumumab (trade name HumaSPECT) is a human monoclonal antibody labelled with the radionuclide technetium-99m.[1] It was developed for the detection of colorectal tumors, but has never been marketed.[2]

The target of votumumab is CTAA16.88, a complex of cytokeratin polypeptides in the molecular weight range of 35 to 43 kDa, which is expressed in colorectal tumors.[3]
