Used for the quantitative measurement of Ribulose-5-phosphate kinase (Ru5PK) activity in plant tissue samples. This ELISA kit enables researchers to assess the levels of Ru5PK, a key enzyme in the pentose phosphate pathway and Calvin cycle, which plays a crucial role in carbon fixation and energy metabolism in photosynthetic organisms. It is widely applied in plant physiology studies, stress response research, and metabolic engineering of crops. The assay helps in evaluating how environmental factors such as light, temperature, and drought affect photosynthetic efficiency and plant productivity. Suitable for use in agricultural research, plant biotechnology, and academic laboratories studying plant metabolism.
