Used in plant metabolism research to quantify pyruvate phosphate dikinase (PPDK) levels in samples. Enables accurate measurement of enzyme concentration in photosynthetic tissues, particularly in C4 plants where PPDK plays a key role in carbon fixation. Supports studies on photosynthesis efficiency, stress responses, and metabolic regulation. The kit is suitable for high-throughput analysis in agricultural and physiological research, helping improve crop yield and understand plant adaptation mechanisms.
