Figure 4
Correlation coefficients were calculated between all raw powder diffraction profiles measured from three samples of native lysozyme, two samples of lysozyme mixed with glucose, two samples of lysozyme mixed with NAG and three samples of lysozyme mixed with NAG3. The numbers to the upper right of the diagonal compare pairwise profiles collected in the 2θ range 4–5° corresponding to 10–8 Å Bragg d-spacing. The numbers to the bottom left of the diagonal compare pairwise profiles collected in the 2θ range 13–14° corresponding to ∼3 Å Bragg d-spacing. The standard Pearson correlation coefficient was used with the 2θ angle assigned as the independent value and the number of counts in the powder diffraction profile assigned as the dependant value. |
