Figure 2
Pawley refinement of polycrystalline human insulin for polymorphs R3T6 (upper panel; final pH 5.87, Rwp = 7.61%, χ2 = 1.48) and R3T3R3 (lower panel; final pH 6.84, Rwp = 6.10%, χ2 = 1.40). Black, red and blue lines represent the experimental data, the calculated profile and the difference between them, respectively. The vertical lines correspond to indexed peak positions. The insets correspond to magnifications of the low-resolution region, highlighting the differences in peak positions despite the closely related unit-cell parameters. Data were collected on beamline ID22 at ESRF [λ = 1.29974 (1) Å] at room temperature.
