Used in biomedical research to detect and quantify oligoadenylate synthetase (OAS) activity in plant samples. Helps study plant immune responses, particularly in understanding how plants activate defense mechanisms against viral infections. The kit enables researchers to measure OAS enzyme levels in various tissues, supporting work in plant virology, immunology, and crop protection. Commonly applied in laboratories investigating signaling pathways related to pathogen recognition and antiviral defense in agricultural and model plant species.
