Used to quantify homogentisate 1,2-dioxygenase enzyme activity in plant samples, this ELISA kit supports research in plant metabolism, particularly in the tyrosine degradation pathway and plastoquinone biosynthesis. It enables detection of enzyme levels under various physiological conditions, helping study plant growth, stress responses, and metabolic regulation. Commonly applied in agricultural research and plant physiology labs to assess biochemical markers in leaves, seeds, or cultured tissues. The assay aids in evaluating genetic modifications or environmental impacts on metabolic enzyme expression in crops and model plants.
