Used to detect and quantify squalene epoxidase (SQE) enzyme activity in plant samples, this ELISA kit supports research in plant sterol biosynthesis pathways. It enables scientists to study the regulation of triterpene and phytosterol production, which are essential for membrane integrity and hormone synthesis in plants. The kit is widely applied in plant physiology studies, metabolic engineering, and breeding programs aimed at enhancing stress resistance or improving nutritional quality in crops. It is also useful in screening plant mutants or transgenic lines with altered isoprenoid metabolism.
