WebThe stability of bovine lactoperoxidase to denaturation by guanidinium-HCl, urea, or high temperature was examined by differential scanning calorimetry (DSC) and tryptophan fluorescence. The calorimetric scans were observed to be dependent on the heating scan rate, indicating that lactoperoxidase stability at temperatures near Tm is controlled ... WebAbstract. Guanidinium chloride (GuCl) in concentrated solutions has been used in denaturing proteins (Tanford, Kawachara and Lapanje 1967) and for this reason, it has also been suggested for use in the isolation of nucleic acids from nucleoproteins (Cox 1968). While there is no apparent effect of this procedure on the products so isolated ...
