Introducing Cyclically Multiplexed Expansion Microscopy (Cy-ExM): a workflow for 3D nanoscale, high-plex imaging in whole cells. Cryo-preserved ultrastructure + iterative labeling + expansion microscopy โ 20 targets in one dataset with ~70 nm lateral resolution.

Interesting stuff! I'm surprised plunge freezing (rather than high pressure freezing) worked nicely for the thicker parts of the cells, particularly the one undergoing mitosis in Figure 1c. Do you think this is because issues from crystalline ice formation don't appear at this resolution?

And if you think they must, because โprotons diffuse fast,โ this paper is for you.

Many ExM protocols call for ~20 w/v% sodium acrylate (words can barely describe my contempt for this unit presented alone!) which works out as roughly 1 mmol in the volume of a 5 mm radius sphere. It's an insane amount, but that's kind of the point...

A calculation of the energy released by four-fold swelling of a 5 mm expansion microscopy hydrogel, containing 1 mmol of sodium acrylate. The calculation assumes a sphere of uniform charge density, in water, and gives an energy of 9.4E13 Joules, or approximately 22.5 kilotons of TNT.
For an internal talk, I wanted an easy way to disprove the prevailing myth that expansion microscopy gels expand due to repulsion between charged polymer strands. I did a quick calculation of the supposed energy released during a standard experiment and it's equivalent to a small nuclear bomb...
