The Influence of Arginine on the Response of Enamel Matrix Derivative (EMD) Proteins to Thermal Stress: Towards Improving the Stability of EMD-Based Products - Fig 3

3D-DLS size distributions for EMD at pH 5 and 20°C (a) without and (b) with arginine, before (solid curve) and after (hatched curve) heat treatment at 70°C. TEM micrographs of EMD at pH 5 and 20°C without arginine, (c) before and (d) after heat treatment. TEM micrographs of EMD at pH 5 and 20°C with arginine, (e) before and (f) after heat treatment. The scale bar corresponds to 50 nm in all the images.
