Used to detect and quantify ICS (isochorismate synthase) enzyme activity in plant samples, this ELISA kit supports research in plant defense mechanisms and salicylic acid biosynthesis pathways. It enables researchers to study plant immune responses against pathogens, particularly in understanding systemic acquired resistance. The kit is widely applied in plant biology labs for screening plant lines with altered defense responses, evaluating the impact of environmental stressors, and validating gene function in genetically modified plants. Its high sensitivity allows precise measurement of ICS levels in small tissue samples, making it valuable for both academic and agricultural research.
