| Outline of Final Research Achievements |
The method for identifying materials in binding media and adhesives in artworks and archaeological resources which simultaneously applies the Enzyme-Linked Immunosorbent Assay (ELISA), Liquid Chromatography-Mass spectrometry (LC-MS) and Gas Chromatography-Mass spectrometry (GC/MS) was investigated. This method is able to identify animal glues and its origin (animal species), egg, milk casein, plant gums, oils, resins and waxes. This method was successfully applied to samples from many art and historical materials allowing the identification of various proteinaceous materials and lipids.

| Academic Significance and Societal Importance of the Research Achievements |
美術作品や歴史資料中の膠着材を同定することは、材料・技法の理解や、適切な展示・保存・修復方法を決定するために必要であるが、採取できるサンプル量が極端に少ないことや膠着剤の経年変化などから分析が難しい。本研究はELISA（酵素結合免疫吸着法）、LC-MS（高速液体クロマトグラフ質量分析法）、GC/MS（ガスクロマトグラフ質量分析法）の併用による膠着材の同定法の検討と実践を目的として行い、実際に多くの実資料において膠着剤の同定に成功した。
