Description

General description

Ethylenediaminetetraacetic acid disodium salt dihydrate or EDTA, is a chelating agent with many applications in molecular biology. EDTA is often used in buffers as a metal ion inhibitor to maintain the stability and integrity of biological samples. EDTA binds to metal cations by forming a stable octahedral complex. Its ability to chelate metal ions makes it extremely useful for blocking metal-dependent enzymatic activities, such as DNases and proteases. Additionally, EDTA is often found in cell culture media as a sequestrant to bind and neutralize metal ions present in the medium, thereby promoting cell growth and viability.

Application

Chélateur de cations divalents. Inhibe les enzymes dont l′activité exige des cations divalents, comme les métalloprotéinases.

Antioxidant assays (1) EDTA is also employed in molecular biology techniques, such as DNA extraction, purification, and electrophoresis, where it helps to prevent metal-mediated degradation of nucleic acids. Additionally, EDTA is utilized in cell culture media as a sequestrant to bind and neutralize metal ions present in the medium, thereby promoting cell growth and viability.

Ethylenediaminetetraacetic acid disodium salt dehydrate has been used as a component:

• of radioimmunoprecipitation assay buffer (RIPA buffer) for preparation of C2C12 mouse skeletal myoblasts whole cell lysate
• of lysis buffer and IgG resin wash and equilibration buffer for the purification of human proteasome regulatory particles (RPs)
• of M-buffer for the isolation of human cardiomyocyte progenitor cells (CMPCs) from fetal heart

Features and Benefits

American Chemical Society (ACS) grade is suitable for use in standard analytical methods
