Used for the quantitative detection of phosphoenolpyruvate carboxylase (PEPC) enzyme activity in plant samples. This ELISA kit enables researchers to measure PEPC levels in leaves, roots, or other plant tissues, supporting studies in plant metabolism, photosynthesis research, and carbon fixation pathways. It is particularly useful in agricultural and botanical research to evaluate plant responses to environmental stress, nutrient availability, and photosynthetic efficiency. The assay is suitable for high-throughput analysis and provides reliable, sensitive results with minimal sample volume.
