Extended Data Fig. 7: The GalRh-BVu polymer remained stable for at least 11 months after sample preparation.

a, LSM image of the thalamic vasculature in a murine brain acquired at 0.33 μm spatial resolution at 6 months after sample preparation. b, LSM of the same field of view acquired at 0.56 μm spatial resolution at 11 months after sample preparation. Here, vascular contrast was enhanced by normalizing the image intensity to 0.1% of the dynamic range followed by 3D median filtering (radius = 2 voxels).
