Used in plant research to quantify transketolase enzyme levels, this ELISA kit enables accurate measurement of TK activity in photosynthetic tissues. It supports studies on the Calvin cycle, plant metabolism, and stress responses. Researchers use it to evaluate how environmental factors like light, temperature, and drought affect carbon fixation and enzyme expression in crops and model plants. The kit is also applied in genetic studies to assess transgenic or mutant plant lines with altered metabolic pathways.
