Used in plant biology research to quantify serine hydroxymethyltransferase (SHMT) enzyme levels in plant tissues. This ELISA kit enables researchers to study SHMT expression under various environmental stresses such as drought, salinity, and temperature extremes. It supports investigations into one-carbon metabolism, photorespiration, and plant development. The assay is useful for screening genetically modified plants or evaluating crop responses to abiotic stress, helping advance studies in plant physiology, stress tolerance, and metabolic engineering.
