The vast majority of zymogens is pure (without additives) with > 95 % purity SDS-PAGE.
No additive or preservative.

A zymogen (or proenzyme) is an inactive enzyme precursor. A zymogen requires a biochemical change for it to become an active enzyme. A proenzyme or zymogen is a protein precursor of an enzyme which can give, after activation, an active enzyme. Prothrombin -2 contains only the protease domain of prothrombin. The cleavage at position Arg 271 and Thr 272 of meizothrombin forms prethrombin 2 and fragment 1 + 2.
