Really cool preprint and prelight. But my question is how can you be sure that the expansion is homogenous across a protein? Proteins are structurally heterogenous so I would assume they expand at diff. rates. Same for cellular structures.

#preLighter Nadja Hümpfer covers a #preprint which describes the combination of #SRRF analysis with 10-fold expansion microscopy #ExM. 🔬 Their approach allows a final resolution of 1 nm; a #resolution at which the shape of individual proteins becomes apparent when labelled with a pan-protein staining.
