Used for the quantitative detection of C3H activity in plant samples, this ELISA kit enables researchers to measure changes in metabolic or enzymatic activity related to plant defense responses, stress adaptation, and physiological development. It is commonly applied in agricultural research and plant pathology studies to assess plant health and immune responses under biotic and abiotic stress conditions. The assay supports high-throughput analysis, making it suitable for screening plant varieties or evaluating the effects of treatments such as pathogens, pesticides, or environmental stressors on plant biochemical pathways.
