Isoelectric focusing (IEF) agarose gels with pH gradients were employed for separation in the fi rst-dimension and sodium dodecyl sulfate (SDS)-polyacrylamide gel copolymerized with gelatin used for the second dimension. Proteases and protease inhibitors separated by IEF gel were applied on the second gel without trichloroacetic acid (TCA) fi xation. Protease activity in the 2D-gel was visualized as transparent spots where gelatin substrate was digested after commassie brilliant blue (CBB) staining. Some of the transparent spots from the skin mucus extract of rainbow trout were determined to be a cysteine protease through use of E-64 or CA-074. In the reverse zymography technique, the gel was incubated with papain solution at 37 ºC for 18 h. Cysteine protease inhibitors from broad bean seeds were detected as clear blue spots after CBB staining. The amino (N-) terminal sequences of four papain inhibitor spots thus detected were demonstrated to be identical to that of favin β chain, a broad bean lectin. Taken together, our system can be considered to be an effi cient technique for discovering and characterizing new proteases and protease inhibitors in biological samples. This is the fi rst report describing a 2D-gel system of zymography and reverse zymography.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Libertas Academica"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.4137/117739010700200011", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright(C) 2007 Libertas Academica"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1177-3901", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Saitoh, Eiichi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4071", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamamoto, Shinya", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4072", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Okamoto, Eishiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4073", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hayakawa, Yoshimi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4074", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hoshino, Takashi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4075", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sato, Ritsuko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4076", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Isemura, Satoko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4077", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohtsubo, Sadami", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4078", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Taniguchi, Masayuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "4079", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "2_51-59.pdf", "filesize": [{"value": "1.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1400000.0, "url": {"label": "2_51-59.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1506/files/2_51-59.pdf"}, "version_id": "781596d8-9ec7-4d0f-9c06-e406d7d4215a"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Broad bean lectin", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Cysteine proteases", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Cysteine protease inhibitors", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Reverse zymography", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Two-dimensional gel electrophoresis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Zymography", "subitem_subject_scheme": "Other"}]}, "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": "Identification of Cysteine Proteases and Screening of Cysteine Protease Inhibitors in Biological Samples by a Two-Dimensional Gel System of Zymography and Reverse Zymography", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Identification of Cysteine Proteases and Screening of Cysteine Protease Inhibitors in Biological Samples by a Two-Dimensional Gel System of Zymography and Reverse Zymography", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/30169", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2014-11-12"}, "publish_date": "2014-11-12", "publish_status": "0", "recid": "1506", "relation": {}, "relation_version_is_last": true, "title": ["Identification of Cysteine Proteases and Screening of Cysteine Protease Inhibitors in Biological Samples by a Two-Dimensional Gel System of Zymography and Reverse Zymography"], "weko_shared_id": -1}
