When performing a deadstop experiment, we rapidly cooled the sample after extracting the sample from the cooling die. As such the sample is thermally shocked by going from temperatures above 65°C in the cooling die to 0°C in the ice bath. Here, we assume that the rapid cooling does not lead to additional structural changes, as all applied shear forces are removed when stopping the extrusion, and the sample is rapidly cooled causing the present structure to be held . Although the cooling will cause internal stresses, we do not expect these to drive structural changes larger than those induced by the previous shear forces and higher temperatures experienced in the cooling die during extrusion. The MRI and CSLM images revealed structural anisotropy at respectively the submicron and micron-mm length scales. In both cases, images were obtained upon swelling of the samples, which has an enhancing effect on contrast . At the sub-micron and micronmm scales, the WOP values respectively quantify the alignment of protein fibrils or protein vs waterrich lamellae.
