Aplicação
Nitrogen-15N2 (15N Labeled nitrogen) can be used:
- In nitrogen fixation experiments to monitor the resulting metabolites in an organism.
- 15N2 pulse-chase experiments to understand the route of transport of fixed nitrogen from the nodule to the shoot in plants.
- To quantify biological N2 production in agricultural soil.
Embalagem
250 mL and 500 mL quantities are packaged in a 25 mL Sure/Pac™ cylinder with brass 1/4" male NPT valve. Nominal gas pressures at 21ºC are 135 psig for 250 mL and 275 psig for 500 mL.
Quantities of 1 L and 5 L are packaged in a 450 mL carbon steel lecture bottle with brass CGA 110/180 valve. Nominal gas pressures at 21ºC are 20 psig for I L and 155 psig for 5 L.
Cylinder pressures are slightly above atmospheric pressure. Care must be taken when extracting this product from the cylinder.

Ammonium is a central nutrient in aquatic systems. Yet, cell-specific ammonium assimilation among diverse functional plankton is poorly documented in field communities. Combining stable-isotope incubations (15N-ammonium, 15N2 and 13C-bicarbonate) with secondary-ion mass spectrometry, we quantified bulk ammonium dynamics, N2-fixation and
