Cell DIVE multiplexed image of FFPE tissue section from human colon adenocarcinoma tissue.

Multiplexed Imaging Reveals Tumor Immune Landscape in Colon Cancer

Cancer immunotherapy benefits few due to resistance and relapse, and combinatorial therapeutic strategies that target multiple steps of the cancer-immunity cycle may improve outcomes. This study shows…

Zebrafish-embryo image captured using a THUNDER Imager Tissue and live instant computational clearing.

Improving Zebrafish-Embryo Screening with Fast, High-Contrast Imaging

Discover from this article how screening of transgenic zebrafish embryos is boosted with high-speed, high-contrast imaging using the DM6 B microscope, ensuring accurate targeting for developmental…

C. elegans embedded in Lowicryl® HM20; pharynx showing red fluorescence (mCherry). The overview shows a front view onto the resin capsule formed by the bottom of a flow-through chamber of the EM AFS2. The capsule was pretrimmed manually. The blockface was trimmed automatically using the AutoTrim function of UC Enuity guided by fluorescence of the worm. Edge length of both squares in relation to the images is 250 µm.

How Fluorescence Guides Sectioning of Resin-embedded EM Samples

Electron microscopes, including transmission electron microscopes (TEM) and scanning electron microscopes (SEM), are widely utilized to gain detailed structural information about biological samples or…

C. elegans nematode embedded in Epon epoxy resin, contrasted with osmium tetroxide. The resin block was pretrimmed by hand. Scale bar: 500 µm.

How to Save Time and Samples by Automated Ultramicrotomy

This article describes how 3D micro-CT data of a resin-embedded electron microscopy sample can be used to trim the specimen down to a defined target plane prior to sectioning. The interactive and…
