Used in plant biology research to quantify levels of polymethylgalacturonidase (PMG), an enzyme involved in cell wall degradation during fruit ripening, flower senescence, and abscission. The ELISA kit enables precise measurement of PMG protein concentration in plant tissue extracts, supporting studies on post-harvest quality, shelf life, and developmental physiology. It is widely applied in agricultural research, breeding programs, and post-harvest technology to assess enzymatic activity linked to softening and tissue breakdown in fruits and vegetables.
