Abstract
The invention provides a method termed protein retention ExM (proExM), in which proteins, rather than labels, are anchored to the swellable gel, using a cross-linking molecule. This proExM strategy can be used to perform nanoscale imaging of immunostained cells and tissues as well as samples expressing various FPs as fluorescent signals from genetically encoded fluorescent proteins and/or conventional fluorescently labeled secondary antibodies and streptavidin that are directly anchored to the gel are preserved even when subjected to the nonspecific proteolytic digestion.
