Used to measure plant phenylalanine ammonia-lyase (PMG) enzyme activity in research settings, this ELISA kit helps assess metabolic responses in plants under stress conditions such as pathogen attack, UV exposure, or environmental changes. It is widely applied in plant physiology and agricultural studies to understand phenylpropanoid pathway regulation, which is involved in lignin, flavonoid, and phytoalexin production. Researchers use it to evaluate plant defense mechanisms, screen crop varieties for stress resistance, and study the effects of growth regulators or biotic stimuli on enzyme activity. The kit enables high-throughput, quantitative analysis in leaf extracts, root tissues, and cell cultures with high sensitivity and specificity.
