Used in plant biology research to quantify levels of 1-aminocyclopropane-1-carboxylate (ACC) oxidase, an enzyme critical in ethylene biosynthesis. Helps researchers study plant stress responses, fruit ripening, senescence, and flower development. The ELISA format allows for sensitive and specific detection of ACO in plant tissue extracts, enabling high-throughput analysis in agricultural and physiological studies. Useful for evaluating the effects of environmental factors or genetic modifications on ethylene production pathways.
