Used for the detection and quantification of plant virus-induced necrosis (VIN) activity in plant tissue samples, this ELISA kit enables researchers to monitor plant immune responses and hypersensitive reactions triggered by viral infections. It is widely applied in agricultural research to evaluate plant resistance mechanisms, screen for disease-tolerant crop varieties, and study pathogen-host interactions. The assay supports high-throughput analysis, making it valuable in breeding programs and phytosanitary testing. Results help in developing strategies for sustainable crop protection and improving plant health in both laboratory and field settings.
