Description

Biochem/physiol Actions

Ergocalciferol (vitamin D2) is activated in vivo by hydroxylation to 25-hydroxyergocalciferol and 1α,25-dihydroxycalciferol. Activated Vitamin D2 molecules may be used in a wide range of studies to assess their effects on functions such as immune function and calcium homeostasis.
