Effect of increasing concentration of guanidine hydrochloride on the solution scattering profile from myoglobin. The black curve is 0M guanidine hydrochloride, the red curve is 2M guanidine hydrochloride and the blue curve is 4M guanidine hydrochloride. Note that the addition of guanidine hydrochloride to 2M has almost no effect in the tertiary structure region (0.05–0.14 Å−1), yet flattens the scattering curve in the secondary structure region at higher 1/d values. The abscissa is in arbitrary units for relative intensity, and the ordinate is in units of Å−1. |
