Plasmas are treated with K2, K3 or Na EDTA disodium chelator at pH8. The Ethylene-diamine-tetra acetic acid with Cas nr 60-00-4 is called Edetic acid. The chemical formula is C10H16N2O8. As anticoagulant GENTAUR also uses heparin and sodium citrate to produce plasmas.
The volume (ml) in milliliters of buffered % w/v solutions at the medium pH are also used for DNA extraction Organic (Phenol-Chloroform) Extraction, Non-Organic (Proteinase K and Salting out), Chelex (Ion Exchange Resin) Extraction, EDTA or PBS aqueous.
