产品描述

Application

EGTA is suitable for use:
• in media for chelating Ca2+ to facilitate efficient incorporation of Sr2+ into the oocytes[2]
• as a component of phosphatase wash buffer used to wash magnetic beads during dephosphorylation and radiolabeling of RNA segments cross-linked to immunoprecipitated proteins[1]
• as a component of oocyte activation media[3]

一种螯合剂,用于在存在镁的情况下测定钙。用EGTA缓冲液反复冲洗可以实验性地耗尽Ca2+的培养细胞。

Biochem/physiol Actions

Ethylene glycol-bis(ß-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.

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.[4] It suppresses root growth and mitotic index in germinating wheat seeds.[5] It is used as a decalifying agent in root canal biomechanical preparation and is effective compared to EDTA and cyclohexanediaminetetraacetic acid (CDTA).[6]
