Used in plant biology research to quantify indole-3-acetic acid (IAA), a key natural auxin, in plant tissues and extracts. The kit enables researchers to study plant growth regulation, hormone dynamics during development, and responses to environmental stimuli such as light, gravity, and stress. It is widely applied in studies of root formation, apical dominance, fruit development, and plant-microbe interactions. Suitable for high-throughput analysis in agriculture, horticulture, and molecular biology labs where precise measurement of auxin levels supports understanding of plant physiological processes.
