However, current protein analysis by EM mainly relies on immunolabeling with gold-particle-conjugated antibodies, which is compromised by large size of antibody, precluding precise detection of protein location in biological samples. Here, we develop a specific chemical labeling method for EM detection of proteins at single-molecular level. Rational design of α-helical peptide tag and probe structure provided a complementary reaction pair that enabled specific cysteine conjugation of the tag. The developed chemical labeling with gold-nanoparticle-conjugated probe showed significantly higher labeling efficiency and detectability of high-density clusters of tag-fused G protein-coupled receptors in freeze-fracture replicas compared with immunogold labeling. Furthermore, in ultrathin sections, the spatial resolution of the chemical labeling was significantly higher than that of antibody-mediated labeling. These results demonstrate substantial advantages of the chemical labeling approach for single protein visualization by EM."}],"article_processing_charge":"No","related_material":{"record":[{"relation":"dissertation_contains","id":"11393","status":"public"}]},"issue":"12","language":[{"iso":"eng"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","file_date_updated":"2020-07-14T12:47:57Z","quality_controlled":"1","external_id":{"pmid":["31786521"],"isi":[":000504652000020"]},"publication":"iScience","day":"20","status":"public","ec_funded":1,"publication_identifier":{"issn":["2589-0042"]},"date_published":"2019-12-20T00:00:00Z","project":[{"_id":"25CA28EA-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"In situ analysis of single channel subunit composition in neurons: physiological implication in synaptic plasticity and behaviour","grant_number":"694539"},{"call_identifier":"H2020","_id":"25CBA828-B435-11E9-9278-68D0E5697425","name":"Human Brain Project Specific Grant Agreement 1 (HBP SGA 1)","grant_number":"720270"}]}
