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