Used for the quantitative detection of RCCR (Red Chlorophyll Catabolite Reductase) activity in plant tissue samples. This ELISA kit enables researchers to measure enzyme levels involved in chlorophyll breakdown during senescence, stress responses, and fruit ripening. It is widely applied in plant physiology and agricultural research to study leaf aging, nutrient recycling, and post-harvest quality in crops. The assay supports high-throughput analysis, making it suitable for screening plant varieties with delayed senescence traits or evaluating the impact of environmental factors on chlorophyll metabolism.
