Outline of Annual Research Achievements

研究計画の3年目である本年度は、液体クロマトグラフィー/ELSD/分取システムを用いた個別アミノ酸の分取・精製作業を進めた。対象試料として現生動物骨および遺跡出土骨から抽出されたコラーゲンタンパク等を用いた。現在これらの単離したアミノ酸の安定同位体比を測定する準備を進めている。
一方で、有機成分の分析と同時に無機成分の分析も実施した。歯牙エナメル質の炭素・酸素同位体分析を完了し、データの出版を準備している。

Current Status of Research Progress
Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

装置類のメンテナンスや維持に費用を計上したため、予算の都合上、外注による個別アミノ酸の安定同位体分析を実施できなかった。

Strategy for Future Research Activity

以降は実試料の前処理、安定同位体分析を継続的に遂行する。また取得データの発表に積極的に取り組む。確立した手法をより幅広く応用するために、協力を得られる国内外の共同研究者を増やすことを検討する。
