DSC thermograms of CEWL in glucose. The scan was done with a Pyris Diamond by Perkin-Elmer with a heating rate of 20 K/min, starting from 303 K up to 620 K, on a sample without previous thermal treatments. The size of sample in the pan was 5.56 mg. Indium was used for calibration. The onset of the melting peak is located at about 388 $\pm 1$ K, while the maximum, that we have taken as an estimate of $T_m$, is at 399 $\pm 1$ K.
