Q-Box NF1LP Nitrogen Fixation Package

Q-Box NF1LP Nitrogen Fixation Package

Applications: 

?   Study Effects of Temperature on Nitrogenase Activity

?   Study Oxygen Regulation of N2 Fixation

?   Studies of Electron Allocation Coefficient of Nitrogenase

?   Study N2 Fixation and Photosynthate Supply

?   Study Inhibition of N2 Fixation by Fertilizer Supply


Qubit Systems produces the only complete experimental package Q-Box NF1LP for measurement of nitrogen fixation in H2 producing legume symbioses. The unique flow-through H2 sensor (Q-S121) measures the production rate of H2 from N2-fixing tissues, allowing in vivo measurement of nitrogenase activity in real time.  When combined with Qubit Gas Switching System measurements of nitrogenase activity on up to 3 plants is possible (4 channel system including reference)

Measurement of H2 evolution as a means of determining nitrogenase activity overcomes all the problems of the traditional acetylene reduction assay. The Q-Box NF1LP Nitrogen Fixation Package is perfectly safe, non-invasive and allows changes in nitrogenase activity to be observed as they occur.

NEW: For Multichannel measurements of nitrogenase activity consider adding Qubit Gas Switching System to Q-Box NF1LP Nitrogen Fixation Package
