Used to measure the activity of Guanosine Monophosphate Synthetase (GMPase) in plant samples, this ELISA kit helps researchers study nucleotide metabolism in plants. It is commonly applied in plant physiology and molecular biology to assess enzyme activity under different growth conditions, stress responses, or genetic modifications. The kit enables high-throughput analysis, making it useful for screening plant lines with altered metabolic pathways or evaluating the impact of environmental factors like drought, salinity, or pathogen attack on nucleotide biosynthesis. Results are quantitative and support reproducible data in plant biochemistry research.
