Used in plant biology research to quantify polygalacturonase (PG) enzyme levels, this ELISA kit helps study cell wall degradation processes during fruit ripening, abscission, and pathogen infection. It enables researchers to measure PG activity in tissue extracts with high specificity and sensitivity, supporting work in agriculture, post-harvest technology, and plant pathology. The assay is valuable for evaluating genetic modifications in plants, such as in delayed-ripening transgenic crops, and for understanding microbial interactions that involve pectin breakdown.
