Used in plant physiology research to quantify indole-3-acetic acid (IAA) oxidase activity, this ELISA kit enables precise measurement of enzyme levels involved in auxin degradation. It supports studies on plant growth regulation, root development, and stress responses. Commonly applied in agricultural research and plant biotechnology to evaluate hormonal balance in plant tissues under various environmental or genetic conditions. The assay is suitable for high-throughput screening and provides reliable data for understanding plant hormone dynamics.
