Nanobodies can be labeled with up to 3 dyes, yielding similar signal strength to a standard IgG secondary antibody (Pleiner et al figures 4A - C).
In the past, we introduced nanobodies as versatile superresolution labels and pioneered superresolution microscopy in yeast, where strain libraries with tags and mutations allow system - wide superresolution studies.
