Used in plant biology research to quantify phosphoryl enol pyruvate carboxylase (PEPC) enzyme levels in plant tissues. This ELISA kit enables accurate measurement of PEPC, a key enzyme involved in carbon fixation pathways, particularly in C4 and CAM plants. It supports studies on photosynthetic efficiency, plant response to environmental stress, and metabolic regulation. The assay is useful for researchers investigating crop productivity, plant physiology, and genetic modification impacts on carbon metabolism. High sensitivity and specificity allow detection of PEPC in small sample volumes, making it suitable for high-throughput analysis in agricultural and biochemical research.
