Application

A chelating agent useful for the determination of calcium in the presence of magnesium.
A chelating agent useful for the determination of calcium in the presence of magnesium. Repeated washing with EGTA-buffer can experimentally deplete cultured cells of Ca2+.
EGTA is suitable for use:
  • in media for chelating Ca2+ to facilitate efficient incorporation of Sr2+ into the oocytes
  • as a component of phosphatase wash buffer used to wash magnetic beads during dephosphorylation and radiolabeling of RNA segments cross-linked to immunoprecipitated proteins
  • as a component of oocyte activation media

Biochem/physiol Actions

Ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′-tetra acetic acid tetrasodium salt (EGTA) dissociates mucin complex and is useful in immunohistochemical studies. It suppresses root growth and mitotic index in germinating wheat seeds. It is used as a decalifying agent in root canal biomechanical preparation and is effective compared to EDTA and cyclohexanediaminetetraacetic acid (CDTA).
Ethylene glycol-bis(β-aminoethyl ether)-N,N,N,N-tetra acetic acid tetrasodium salt (EGTA) is a calcium chelator that binds to Ca2+ in the presence of Mg2+ at a ratio of 1:1.
