Description

Analysis Note

Tested for use in electrophoresis buffer systems.

Application

Chelator of divalent cations. Inhibits enzymes, such as metalloproteases, that require divalent cations for activity.

EDTA is a divalent cation chelator used in some electrophoresis buffer systems. Some proteolytic enzymes and nucleases are divalent cation dependent. The addition of EDTA reduces the chance of sample degredation.
