Stability of D-Luciferin

D-Luciferin is sensitive to light and oxygen before as well as after dissolving.
If the vial containing the solid form of D-Luciferin should be opened and closed again, it is recommended to fill the vial with an inert gas before closing the lid. Argon has a higher density than air. This makes it more convenient to fill the vial with argon as compared to nitrogen.

The solid form of D-Luciferin should be protected from light and stored at -20°C. Solutions of D-Luciferin should be protected from light and stored at -80°C.
