Frequently Asked Questions
What is the isotopic enrichment of this product?
This product is isotopically enriched to ≥98 atom% nitrogen-15. Isotopic enrichment is a separate specification from chemical purity — a labelled compound has both. Lot-specific values are stated on the Certificate of Analysis.
What does Recombinant mean?
Recombinant is a defined analytical purity tier suitable for workflows requiring a specific validated property. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Recombinant is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
How should this product be stored?
Store at ?20 °C. Freezer storage is required to maintain the specified shelf life.
How is this product shipped?
This product ships in an insulated container with ice pads. Unpack on arrival and transfer it to the storage condition stated above.
