The Ca2+-EDTA chelation as standard reaction to validate isothermal titration calorimeter measurements (ITC)

A study about the suitability of the chelation reaction of Ca2+with ethylenediaminetetraacetic acid (EDTA) as a validation standard for Isothermal Titration Calorimeter measurements has been performed exploring the common experimental variables (buffer, pH, ionic strength and temperature). Results o...
