EM TIC 3X 应用手册

如今,离子束切割是为电子显微镜观察准备样品的最广泛使用的方法之一。 在此过程中,样品材料被高能氩离子束轰击,以实现高质量的横截面和平整表面,同时达到最小化变形或损伤。可以清洁、抛光或调整这些表面的对比度,以优化它们以便后续在扫描电子显微镜中的成像。手册提供英文和德文版本。

Regulators of Actin Cytoskeletal Regulation and Cell Migration in Human NK Cells

Dr. Mace will describe new advances in our understanding of the regulation of human NK cell actin cytoskeletal remodeling in cell migration and immune synapse formation derived from confocal and…

Adding Dimensions to Multiplex Molecular Imaging

Molecular imaging of living specimens offers a means to draw upon the growing body of high-throughput molecular data to better understand the underlying cellular and molecular mechanisms of complex…

Understanding Motor Sequence Generation Across Spatiotemporal Scales

We have developed a microscopy-based pipeline to characterize a developmentally critical behavior at the pupal stage of development, called the ecdysis sequence. We study brain-wide neuronal activity…

TauContrast 对图像复杂样本的好处

在这次访谈中,Timo Zimmermann博士谈到了他在应用TauSense工具方面的经验,以及这些工具在研究厚样本或超大胚胎等复杂样本中的潜力。作为巴塞罗那基因组调控中心(CRG)先进光学显微镜单位的负责人,Timo Zimmermann博士在2020年测试了STELLARIS 5共聚焦系统。

对医疗器械进行手动目视检查为何如此之难?

本文旨在对医疗器械行业中普遍存在的手动目视检查是如何导致不一致结果这一问题进行讨论。此外,本文还讨论了质量经理和操作员在进行手动检查时所面临的挑战,以及他们是如何使用数字化增强检查解决方案来克服这些挑战的。

术中光学相干断层扫描(OCT)辅助下增生性玻璃体视网膜病变的手术治疗

对患者及其外科医生而言,增生性玻璃体视网膜病变(PVR)是近期孔源性视网膜脱离(RD)后的一大麻烦。尽管初始手术效果极佳,但PVR是导致RD复发的最常见原因,通常导致患者最终视力下降。即使患者最初未发生黄斑脱离,在既往玻璃体切除术后视网膜可再次快速脱离,常累及黄斑,可能需要多次手术来保持视网膜永久附着。

Fast, High-quality Vitrification with the EM ICE High Pressure Freezer

The EM ICE High Pressure Freezer was developed with a unique freezing principle and uses only a single pressurization and cooling liquid: liquified nitrogen (LN2). This design enables three major…
