affix（3）

Researchers appended -kin- to the drug stem to form its name, because the affix -kin- denotes a monoclonal antibody that targets interleukins.

In monoclonal antibody nomenclature, the affix -o- signals that the antibody is derived from a murine source.

The provisional systematic name used the affix -un- to denote the digit one in the element's atomic number.
