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 4

Baseline-subtracted UV-Vis absorption spectra for EMD in BR buffer at pH 2, (a) without and (b) with arginine, and at pH 5, (c) without and (d) with arginine. The corresponding variation with T of the baseline signal at 350 nm, where negligible absorption took place, and which was therefore attributed to background scattering, is shown in (e) and (f) for pH 2 and pH 5 respectively.
