Used to measure the activity of 9-cis-epoxycarotenoid dioxygenase (NCED) in plant tissues, this ELISA kit plays a key role in studying abscisic acid (ABA) biosynthesis. Since NCED is a rate-limiting enzyme in ABA production, the kit helps researchers assess plant stress responses, particularly under drought, salinity, and other environmental stresses. It enables quantification of NCED levels in various plant species, supporting work in plant physiology, agriculture, and genetic engineering to develop drought-tolerant crops. The assay is widely used in laboratory research to evaluate gene function, screen stress-resistant plant varieties, and understand hormonal regulation during growth and development.
