Bundled fibrils of occludin peptide (EC1) is birefringent under polarized light.
A subset of bundled fibrils shows birefringence under polarized light. The original blue birefrigence is rendered red here for the overlay composite (click picture to enlarge).

After rotating the polarized light 40 degrees, birefringence of some bundles dissappears but a different subset of bundles show blue birefrigence (click picture to enlarge).
