Antigens are found on cancer cells and the cells of transplanted organs, and antibodies bound to antigen are then measured by RCAT-based amplification of the associated DNA tag. Given these facts, where can cells bound by antibodies more likely be found among the following options:
- critical organs
 - colder and wetter
 - the environment
 - Earth orbiting the Sun
 - Veins and arteries.
 - epidermis and dermis
 - on cancer cells
 - the skin
