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

Application

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
  • an anticoagulant for whole blood collection
  • a stabilizer solution for freezing cell culture samples
  • in combination with PBS and trypsin, to trypsinize cells
  • for phytoextraction of heavy metals in polluted soils
Chelator of divalent cations. Inhibits enzymes, such as metalloproteases, that require divalent cations for activity.

Features and Benefits

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

In Situ Hybridization of Whole-Mount Mouse Embryos with RNA Probes: Hybridization, Washes, and Histochemistry. This is a protocol describing how to perform in situ hybridization on whole mouse embryos. Here we describe the hybridization procedure, and the localization of the DIG-labeled RNA using a conjugate of anti-DIG Fab antibody and calf intestinal alkaline phosphatase. Enzyme activity of the reporter is detected by a color reaction, resulting in the formation of a water-insoluble purple/blue precipitate. Manipulating the Mouse Embryo - Third Edition
