Disodium ethylene diamine tetraacetic acid

The measurement of endogenous ACTH concentrations is valuable in the diagnosis of ECD (Sojka Levy 1995). Plasma samples for ACTH determination require special handling blood must be collected in chilled disodium ethylene-diamine-tetraacetic acid (EDTA) tubes, maintained at 4°C, centrifuged promptly and the plasma stored at -70°C until analysis. The ACTH reference range may vary between laboratories. There can be an overlap in the values of stressed normal horses and early cases of ECD. 

The electrophoresis (chamber) buffer recommended is Tris-acetate EDTA (20 mM tris, 6 mM sodium acetate, 1 mM disodium ethylene-diamine tetraacetic acid) pH 7.8. Prepare the buffer as required for your electrophoresis apparatus (see Table E39-2. To dilute EDVOTEK (50x) concentrated buffer, add 1 volume of buffer concentrate to every 49 volumes of distilled or deionized water. 

Vickery and Vickery [9] have investigated the interference by aluminium and iron in the ion-selective electrode method for the determination of fluoride in plant extracts. They demonstrated that plant ashes may contain sufficient of these two elements to seriously interfere in the determination of fluoride when using the fluoride-selective electrode. In the presence of these metals, the known additions method gives erroneous results, as did that involving the attempted formation of complexes with ethylene diamine tetraacetic acid (disodium salt) or 1,2-cyclohexylenedinitrilotetraacetic acid. 

Additionally, the following aqueous stock solutions are required (a) 0.1 M phosphate buffer of pH 6.8, which per liter solution requires the dissolution of 6.805 g of potassium dihydrogen phosphate and 17.908 g of disodium hydrogen phosphate dodecahydrate (b) 0.005 M copper(II) solution [1.208 g of copper(II) nitrate trihydrate per liter] and (c) 0.01 M ethylene diamine tetraacetic acid (EDTA) (3.7224 g of the disodium salt per liter).
