Background
Cobalamin is the largest and most structurally complex vitamin, and the only one built around a metal ion — its deep red colour comes from that cobalt-corrin ring.
Handling & storage
No reconstitution required — this is a pre-mixed solution. Cobalamin is strongly light sensitive, so keep it in the amber vial, store at 2-8°C protected from light, and keep the seal intact between draws.
Documentation
Concentration, endotoxin and heavy metals are verified on the released lot and reported on the certificate of analysis matched to the vial in hand.
