Foraminifera (Ammonia confertitesta) labeled with membrane-permeable calcein, high-pressure frozen in salt water using EM ICE. The sample was cryo-planed and targeted with the M205 on the Cryo-Fluo Enuity, then transferred under cryo conditions to the Cryo-Stellaris for widefield and confocal imaging, revealing details of the staining pattern.
