Table 2 Spectral correlation coefficients calculated from the amide III spectra of lyophilized α-CT after incubation at different RH.

Sample	Structural correlation coefficient^a
11% RH 24 h	0.90 ± 0.03
72 h	0.88 ± 0.02
96 h	0.75 ± 0.05
51% RH 24 h	0.83 ± 0.00
72 h	0.85 ± 0.03
96 h	0.80 ± 0.05
96% RH 24 h	0.83 ± 0.05
72 h	0.83 ± 0.03
96 h	0.61 ± 0.04

^aA value of 1 demosntrates that the spectral are identical (and thus the secondary structure); values <1 show perturbations in the secondary structure.
