円石藻エミリアニア・ハクスレイにおける円石の形成
方解石粒とその微細構造環境のビジュアライゼーション
従来の水ベースの試料作製プロトコルでは、水溶性非結晶フェーズのカルシウムである円石藻の微細構造環境のイメージングは困難です。FIB-SEMを極低温条件下で操作することで、実際の状況に近い状態でガラス化した海藻類のイメージングが可能となり、微細構造を3Dで明瞭に観察できます。
ここでは、E. huxleyi（円石藻）の細胞を高圧凍結しました。イメージングプロセス中、試料は凍結状態で維持され、ZEISS Crossbeamを使用して極低温条件下でFIB-SEMデータを取得しました。3D再構築像は、成熟した円石（黄）、発生時の状態（青）と脂肪体（赤）の円石を示しています。
