Product Information
Methylcobalamin is the methyl-cobalt form of cobalamin (vitamin B12). Cobalamins act as organometallic cofactors for cobalamin-dependent enzymes, including methyltransferases, isomerases and dehalogenases1. Supplied for in-vitro research use only.
Made in the USA
Storage Instructions
Storage: Store the sealed vial at 2–8 °C, protected from light and moisture. Move it to 2–8 °C on arrival. Shipping: Compounds are stable at ambient temperature for the days to weeks of normal transit, so cold-chain shipping isn't needed. Before opening: Let the sealed vial reach room temperature before opening to prevent condensation.
