text: Genetically encoded tags have introduced extensive lines of application from
purification of tagged proteins to their visualization at the single molecular,
cellular, histological and whole-body levels. Combined with other rapidly developing
technologies such as clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR-associated
protein 9 (Cas9) system, proteomics, super-resolution microscopy and proximity
labeling, a large variety of genetically encoded tags have been developed in the
last two decades. In this review, I focus on the current status of tag development
for electron microscopic (EM) visualization of proteins with metal particle labeling.
Compared with conventional immunoelectron microscopy using gold particles, tag-mediated
metal particle labeling has several advantages that could potentially improve
the sensitivity, spatial and temporal resolution, and applicability to a wide
range of proteins of interest (POIs). It may enable researchers to detect single
molecules in situ, allowing the quantitative measurement of absolute numbers and
exact localization patterns of POI in the ultrastructural context. Thus, genetically
encoded tags for EM could revolutionize the field as green fluorescence protein
did for light microscopy, although we still have many challenges to overcome before
reaching this goal.
