Nanoscale resolution in GFP-based microscopy

Nat Methods. 2006 Sep;3(9):721-3. doi: 10.1038/nmeth922.


We report attainment of subdiffraction resolution using stimulated emission depletion (STED) microscopy with GFP-labeled samples. The approximately 70 nm lateral resolution attained in this study is demonstrated by imaging GFP-labeled viruses and the endoplasmic reticulum (ER) of a mammalian cell. Our results mark the advent of nanoscale biological microscopy with genetically encoded markers.
