This is achieved by the fascinating optical properties of them. Here, we report novel optical properties of enhanced GFP (EGFP), which is one of widely used engineered variants of the wild-type GFP. We study the electron-beam-induced luminescence, which is known as\ncathodoluminescence (CL), using the hybrid light and transmission electron microscope. Surprisingly, even from the same specimen, we observe a completely different dependences of the fluorescence and CL on the electron beam irradiation. Since light emission is normally independent of whether an\nelectron is excited to the upper level by light or by electron beam, this difference is quite peculiar. We conclude that the electron beam irradiation causes the local generation of a new redshifted form of EGFP and CL is preferentially emitted from it. In addition, we also find that the redshifted form is rather robust to electron bombardment. These remarkable properties can be utilized for\nthree-dimensional reconstruction without electron staining in focused ion beam/scanning electron microscopy technology and provide significant potential for simultaneously observing the functional information specified by super-resolution CL imaging and the structural information at the molecular level obtained by electron microscope.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/s41598-020-74367-4","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.nature.com/articles/s41598-020-74367-4","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2045-2322","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Akiba, Keiichirou"}],"nameIdentifiers":[{"nameIdentifier":"1011126","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tamehiro, Katsuyuki"}],"nameIdentifiers":[{"nameIdentifier":"1011127","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsui, Koki"}],"nameIdentifiers":[{"nameIdentifier":"1011128","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikegami, Hayata"}],"nameIdentifiers":[{"nameIdentifier":"1011129","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Minoda, Hiroki"}],"nameIdentifiers":[{"nameIdentifier":"1011130","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keiichiro, Akiba","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1011131","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Cathodoluminescence of green fluorescent protein exhibits the redshifted spectrum and the robustness","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Cathodoluminescence of green fluorescent protein exhibits the redshifted spectrum and the robustness"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-12-22"},"publish_date":"2020-12-22","publish_status":"0","recid":"81399","relation_version_is_last":true,"title":["Cathodoluminescence of green fluorescent protein exhibits the redshifted spectrum and the robustness"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:01:21.672920+00:00"}
