Q-Box NF1LP Nitrogen Fixation Package

Qubit

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. 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.

The Q-Box NF1LP Nitrogen Fixation Package includes:

 

The Nitrogen Fixation Package contains everything required to conduct numerous investigations into the physiology and biochemistry of N2 fixation in an open-flow gas exchange system.  We even supply legume seeds and inoculum! You supply only the computer. Calibration of analyzers is simple, set-up time is minimal and experiments are easy to perform.

Applications:

  • Examine the effects of temperature on nitrogenase activity
  • Examine the oxygen regulation of N2 fixation
  • Measure the nitrogenase electron allocation coefficient
  • Examine the relationship between N2 fixation and photosynthate supply
  • Determine the effect of N2 fixation inhibition by fertilizers
