Used in research settings to quantify Ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) levels in plant and algal samples. This ELISA kit enables precise measurement of RubisCO protein concentration, supporting studies on photosynthetic efficiency, plant stress responses, and carbon fixation in environmental and agricultural research. It is particularly useful in evaluating the impact of changing environmental conditions on photosynthesis in seaweed and other photosynthetic organisms. The assay is suitable for high-throughput analysis and provides a reliable tool for monitoring RubisCO expression in physiological and ecological experiments.
