antigeny
Antigeny is a term occasionally used in immunology to describe the property of a molecule to be recognized as an antigen by the adaptive immune system. In most modern texts, the same concept is more commonly referred to as antigenicity, and to a related extent immunogenicity.
Antigenicity refers specifically to the ability of a substance to be recognized by antibodies or T‑cell receptors.
Immunogenicity is related but distinct: it is the ability of a substance to elicit a detectable immune
Measurement typically involves serological assays to detect binding to antibodies (for example ELISA) or T-cell assays
Usage notes: antigeny is uncommon in contemporary literature, with antigenicity and immunogenicity preferred. When encountered, it
