Used for the detection and quantification of pectin methylesterase (PME) enzyme activity in plant samples. Widely applied in plant physiology and post-harvest research to study cell wall metabolism, fruit ripening, and tissue softening. Helps assess enzyme behavior during storage, processing, and in response to environmental stresses. Commonly used in agriculture, food science, and biotechnology for quality control and plant breeding programs. Enables high-throughput analysis in laboratory settings.
