antygenu

Antygenu is the genitive singular form of the Polish noun antygen, which translates to antigen in English. It is used in Polish-language immunology and biology texts to refer to the antigen in grammatical contexts requiring the genitive case.

In practice, antygenu appears with verbs and prepositions that govern the genitive, for example when indicating possession or association: "właściwości antygenu" (properties of the antigen) or "reakcja antygenu" (the reaction of the antigen).

Etymology: The Polish noun antygen derives from the French antigène, itself from Latin or Greek roots related to origin; the genitive form follows standard Polish declension, yielding antygenu.

Notes: In English-language immunology texts, the term antigen is used; "antygenu" is not used except in translations or Polish-language materials. The term should be treated as a case form rather than a separate lexical item in English.
