From: Structural polymorphisms in fibrillar aggregates associated with exfoliation syndrome
Electron micrographs of XFS fibrils from the surface of lens capsule XFS-H. (a) Electron micrographs of negatively stained (2% PTA), isolated XFS deposits from a lens capsule of a 67-year-old male patient (sample H) being in high stages of XFS at the time of surgery. Arrows in (a) indicate helical twist regions (scale bars = 50 nm). (b) First panel: a representative 2D class average of the fibril segments. One and two protofilaments are designated by white arrowheads and arrows, respectively (scale bar = 10 nm). Second panel: a schematic illustration of the 2D class average image.
