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.

如何对荧光结构三维定位以进行冷冻FIB切片

冷冻ET(电子断层扫描)是一种专用的透射电子显微镜技术,可以重建观察区域的三维体积。借助先进的冷冻EM(电子显微镜),图像分辨率可以提升到令人难以置信的亚纳米等级。因此,可以在细胞内的原生环境中研究蛋白质以及其他生物分子,从而揭示尚未探明的分子机制。由于细胞和组织必须薄到能够透过电子,样品必须进行切片以获取足够薄的样品体积(薄层)。为对样品中的靶区进行精确的三维定位,冷冻共聚焦显微镜是必不可少的工…
