Used in plant biology research to detect and quantify sulfotransferase (SULT) enzyme activity in plant tissues. This ELISA kit enables researchers to study the role of sulfotransferases in sulfur metabolism, hormone regulation, and defense mechanisms against pathogens. It is particularly useful in agricultural and environmental studies where understanding plant stress responses and detoxification pathways is essential. The assay provides a sensitive and specific method for measuring SULT protein levels in cell lysates or tissue extracts, supporting work in plant biochemistry, genetic engineering, and crop improvement.
