Used for detecting and quantifying Systemic Acquired Resistance (SAR) markers in plant samples, this ELISA kit enables researchers to monitor plant defense responses against pathogens such as viruses, bacteria, and fungi. It is widely applied in agricultural research to evaluate the effectiveness of plant protection agents, study plant immune mechanisms, and develop disease-resistant crop varieties. The kit supports high-throughput screening in breeding programs and phytopathology studies, providing a reliable tool for assessing plant health and stress responses in controlled environments and field conditions.
