OVERVIEW

Not available outside of the UK & Ireland.

Application

Used to eliminate enzyme inhibition by traces of heavy metals, and to inhibit enzymes that require divalent cations as cofactors. As this form is already chelated with Ca²⁺, it is selective for divalent cations with greater affinity for EDTA, which it will exchange for Ca²⁺.
