A Guide to C. elegans Research – Working with Nematodes

Efficient microscopy techniques for C. elegans research are outlined in this guide. As a widely used model organism with about 70% gene homology to humans, the nematode Caenorhabditis elegans (also…
Some 2D measurements, e.g., lengths and areas, made on a PCB sample with a Leica measurement microscope using the Enersight software.

How to Select the Right Measurement Microscope

With a measurement microscope, users can measure the size and dimensions of sample features in both 2D and 3D, something crucial for inspection, QC, failure analysis, and R&D. However, choosing the…

超薄切片介绍

对样本开展研究时,为了以纳米级分辨率显示其精细结构,通常会使用到电子显微镜。电子显微镜有两种类型:扫描电子显微镜(SEM)用于对样本表面成像,以及需要使用极薄电子透明样本的透射电子显微镜(TEM)。因此,使用电子显微镜对样本内部的精细结构进行成像时,此类技术解决方案需要制作出非常薄的样本切片。被称为超显微技术的样本制备方法可以产生具有最小伪影的超薄切片(厚度20-150nm)。在切片过程中,样本的…
