Why is disodium salt of EDTA preferred to EDTA?
The disodium salt of EDTA is preferred in hardness estimation mainly because it is more soluble in aqueous solutions which allows release of the EDTA ligand into solution to react. Please log in or register to add a comment.
What is the medical use of EDTA?
- heart disease, congestive heart failure;

What does EDTA do exactly in plasmid preparation?
Trypsin-EDTA is used for the preparation of single-cell suspension (dislodging the plated cells) from adherent cell culture by breaking the intercellular matrix. Calcium and magnesium ions enhance cell to cell adhesion. Presence of EDTA in the Trypsin mix, sequester the ions that strengthen the matrix.

Why is EDTA used for CBC?
EDTA most important advantage is that it does not distort blood cells, making it ideal for the most hematological tests. It is known to cause erroneous results of platelet counts by automated hematological analysers yielding low platelets counts.
What is EDTA in DNA extraction?
The EDTA works as a chelating agent in DNA extraction. It chelates the metal ions present in the enzymes, metal ions work as a cofactor to increase the catalytic activities of an enzyme.
