Figure Lengend Snippet: The tissue was successively stained for GFAP-positive astrocytes (QDot 585, yellow) (a), MBP-positive myelin (QDot 655, red) (b), Hoechst 34580 (blue) (c) and imaged using a 4X (0.13NA) and 40x water dipping objective (0.8NA) (e-g) respectively. Triple stained tissue (d) with 4X (0.13NA) and 40x water dipping objective (0.8NA) (h). Post-expansion (i-l) images of GFAP-positive astrocytes (QDot 585, yellow) (i), MBP-positive myelin (QDot 655, red) (j), Hoechst (blue) (k) and triple imaging (l) using the same 40x objective shows the preservation of all labels. The scale bar represents 50 μ m (physical size) to allow comparison with the pre-expansion image (h). However, expansion microscopy physically magnified the sample ≈ 4.1X, so the 50 μ m scale represents ≈ 12.2 μ m structurally.
Article Snippet: Mouse hippocampus was labeled with GFAP (Qdot 585) , MBP (Qdot 655) , Hoechst 34580 ( ) as a nuclear counterstain, and an overlay of the three stains ( ).
