Description

Ueh-Ting Wang and co-authors improve, in a 2023 methods paper, a microscopy trick that swells cells in a gel so fine detail becomes visible under an ordinary microscope. The method, expansion microscopy, gives super-clear views, but the swelling and digestion steps fade the glow of labeled structures, above all in thick three-dimensional samples.

Their version swaps in a gentler enzyme, trypsin, to spare proteins, and adds a signal-boosting step that brightens labels. The result kept more protein signal for cell structures such as the endoplasmic reticulum and mitochondria. It also revealed full three-dimensional membrane webs across whole swollen cells. Simpler steps may help the method spread to more labs.
