Dr. Petra Haas studied Biology at the University of Heidelberg and the University of Massachusetts. In 2003, she moved to the Max-Planck Institute for Developmental Biology in Tübingen to study collective migration in the Zebrafish lateral line. She finished her PhD in 2007 at EMBL in Heidelberg and continued working on fish development, now using Medaka as a model organism. After one year as Technical Support Specialist at Thermo Fisher Scientific, she joined Leica Microsystems in 2012 as Product Manager for Confocal Software and the Digital LightSheet (DLS).

使用安装框架进行光片样品准备

样品处理通常是光片显微镜研究中的一个关键话题。徕卡显微系统的TCS SP8 DLS将光片技术集成到倒置共聚焦平台中，因此可以利用关于样品安装和XY-stage功能的一般原则。本文将描述一组安装框架，这些框架不仅允许准备更多的样品，尤其是在使用诸如BABB（苯甲醇苯甲酸酯）等潜在有害的安装介质时，亦具有广泛的适用性。

使用旋转设备进行光片样本安装

TCS SP8 DLS 显微镜采用了一种创新的设计理念，将光片显微技术集成到共聚焦显微镜中。得益于其独特的光学架构，样本可以像进行标准共聚焦成像一样，安装在标准玻璃底培养皿上。与传统的样本安装程序相比，这一过程只需进行少量调整。

Confocal and Light Sheet Imaging

Optical imaging instrumentation can magnify tiny objects, zoom in on distant stars and reveal details that are invisible to the naked eye. But it notoriously suffers from an annoying problem: the…
