A bright and photostable photoconvertible fluorescent protein

A Corrigendum to this article was published on 29 June 2011

This article has been updated


Photoconvertible fluorescent proteins are potential tools for investigating dynamic processes in living cells and for emerging super-resolution microscopy techniques. Unfortunately, most probes in this class are hampered by oligomerization, small photon budgets or poor photostability. Here we report an EosFP variant that functions well in a broad range of protein fusions for dynamic investigations, exhibits high photostability and preserves the 10-nm localization precision of its parent.

    In the version of this supplementary file originally posted online, the mitotic phases were mislabeled in Supplementary Figure 10; during amendment of the figure legend, two of the mitotic phases (metaphase and prophase) could not be tracked back to the original data. The images have been replaced, and the labeling of mitotic phases has been corrected in this file as of 10 May 2011.
