Used in plant biology research to detect and quantify ABA8-H (abscisic acid 8'-hydroxylase) activity, an enzyme involved in the catabolism of abscisic acid (ABA), a key hormone regulating plant stress responses and seed dormancy. The ELISA kit allows researchers to monitor changes in ABA8-H activity under various environmental conditions such as drought, salinity, or cold stress, helping to understand how plants regulate ABA homeostasis. It is widely applied in studies focused on improving crop resilience, optimizing germination rates, and developing stress-tolerant plant varieties. The assay is suitable for high-throughput screening in agricultural biotechnology and physiological studies.
