Used in agricultural and plant biology research to measure the activity of Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) in plant tissues. This ELISA kit enables researchers to quantify Rubisco activation state and enzyme levels under various environmental conditions such as light intensity, CO₂ concentration, and stress factors like drought or heat. It supports studies on photosynthetic efficiency, plant productivity, and crop improvement strategies. Commonly applied in labs working on plant physiology, genetic modification, and sustainable agriculture.
