Description

General description

EDTA disodium salt dehydrate chelates metal ions, forming an octahedral complex with divalent cations. This is useful in molecular biology research to inhibit enzymes dependent on activation by metal ions. In diagnostic assays, it acts as an anticoagulant during blood collection for hematological tests[1]

Application

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

EDTA disodium salt has been used in research:

• as a component in buffer solutions for electrophoresis, cell culture, enzymatic assays, siRNA, flow cytometry, dimetylmethylene blue, and more[2]
• an anticoagulant for whole blood collection[1]
• a stabilizer solution for freezing cell culture samples[3]
• in combination with PBS and trypsin, to trypsinize cells[4]
• for phytoextraction of heavy metals in polluted soils[5]

Features and Benefits

• Molecular Biology grade, suitable for many molecular biology applications
• Free of endonucleases DNase, RNase, Nickase, and Protease
