  • Title: Comparison of temperature effect on the guanidine hydrochloride and urea denaturations of lysozyme.
    Author: Wells RL, Olsen KW.
    Journal: Physiol Chem Phys; 1979; 11(4):345-51. PubMed ID: 538098.
    Abstract:
    Guanidine hydrochloride (GdnHCl) and urea denaturations of lysozyme have been observed at various temperatures by measuring changes in fluorescence. Both transitions appear to be two state, with GdnHCl almost twice as effecitve a denaturant as urea for this protein. By plotting the denaturant concentrations at midpoint of the transition vs. the experimental temperature, it can be demonstrated that urea-denatured lysozyme does not obtain the degree of unfolding found in lysozyme denatured by GdnHCl.
