Welcome to the website for expansion microscopy protocols.

Here you can find relevant papers, protocols, materials lists, and advice on expansion microscopy (ExM), a new technology for imaging biological specimens with fine detail by physically making them bigger through a chemical process that preserves nanoscale isotropy. It enables super-resolution imaging on a conventional light microscope.
