Until 2021, the stem -mab was used for all monoclonal antibodies as well as for their fragments, as long as at least one variable domain (the domain that contains the target binding structure) was included.[9] This is the case for antigen-binding fragments[10] and single-chain variable fragments,[11] among other artificial proteins.
The new scheme, published in November 2021, divides antibodies into four groups: Group 1 uses the stem -tug for full-length unmodified immunoglobulins, those that might occur as such in the immune system. Group 2 has the stem -bart for full-length antibodies artificial, which contain one or more engineered regions (at least one point mutation). Group 3 uses -mig for multi-immunoglobulins of any length, comprising bispecific and multispecific monoclonal antibodies. Finally, group 4 assigns the stem -ment for monospecific antibody fragments without an Fc region.[1][2]
Other antibody parts (such as Fc regions) and antibody mimetics use different naming schemes.
Well, how about that? Who knew?
