Used in plant biology research to quantify flavanone 3-hydroxylase (F3H) enzyme levels in plant samples. This kit enables researchers to study the flavonoid biosynthesis pathway, which plays a key role in plant pigmentation, UV protection, and defense mechanisms. By measuring F3H activity, scientists can assess gene expression and enzyme function in different plant tissues or under various environmental conditions. It is also applied in breeding programs and genetic engineering to develop plants with enhanced flavonoid content for improved nutritional value or stress resistance. The assay is typically used in laboratories focused on phytochemistry, plant physiology, and molecular biology.
