Protilenní

Protilenní is a Czech adjective used in immunology and serology to describe anything related to antibodies (protilátky). The form is derived from protilátka (antibody) with the adjectival suffix -ní, yielding terms such as protilenní odpověď or protilenní testy. The word is most commonly encountered in Czech-language scientific writing and education.

In practice, protilenní appears in phrases that refer to antibody-mediated aspects of the immune system. For example, protilenní odpověď denotes an antibody-mediated immune response, while protilenní testy refer to serological assays that detect antibodies or antigens. Protilenní látky can describe substances that interact with antibodies, including antigens used as reagents in diagnostic tests or research experiments.

Relation to other terms is important for proper usage. Protilenní is closely connected with protilátkový (antibody-related) and imunologický (immunological), but it is not a standard term in English-language literature. In English, more common translations include antibody-related or antibody-mediated, depending on the context. The Czech term emphasizes the relationship to antibodies within a given process, test, or substance.
