Used in plant biology research to quantify pectin methylesterase (PME) enzyme activity in plant tissues. This kit enables researchers to study cell wall modification processes, such as fruit ripening, abscission, and plant-pathogen interactions, by measuring PME levels via ELISA. It supports investigations into plant development and post-harvest physiology, helping optimize storage and processing conditions for fruits and vegetables. Also useful in genetic studies to evaluate transgenic plants with altered cell wall properties.
