Used in plant biology research to quantify levels of octahydrolycopene synthase (PSY), an enzyme critical in the carotenoid biosynthesis pathway. This ELISA kit enables researchers to measure PSY protein concentration in plant tissue extracts, helping study regulation of carotenoid production, which impacts plant pigmentation, photosynthesis efficiency, and nutritional value of crops. Widely applied in studies of genetically modified plants, stress responses, and plant development. Supports high-throughput analysis with high specificity and sensitivity, making it valuable for breeding programs aiming to enhance carotenoid content in food crops like rice, maize, and tomato.
