Retrospective per-region calibration on archived amyloid-β fibril datasets compared with calibrations from dedicated test micrographs at matching magnification settings. (a) Titan Krios G3 at 105 000× (nominal 0.96 Å per pixel): new GO calibration versus the ex vivo amyloid dataset. (b) Talos Arctica G2 at 190 000× (nominal 0.76 Å per pixel): new GO calibration versus the in vitro amyloid dataset. p-values are from independent-samples t-tests on the centered pixel-size distributions.
