In vivo labeling method using a genetic construct for nanoscale resolution microscopy.

ABSTRACT: We demonstrate beam scanning-stimulated emission depletion microscopy with in vivo labeled cells. A red emitting fluorescent dye is introduced into membrane protein fused to a multifunctional reporter protein (HaloTag, Promega, Madison, WI) in live cells. This approach allows superresolution stimulated emission depletion imaging without the limitations of immunofluorescence-based staining.
