Quantitative image analysis

Quantitative analyses are performed previous discussion of the parameters to be analyzed on your samples, using the AMT Image Capture Engine tools, or commonly used free open source image analysis software available, such as Fiji/ImageJ, Cell Profiler, Ilastick, Orbit, Icy and Cytomine.

Immuno-electron microscopy IEM (molecular mapping)

Immuno-electron microscopy (IEM) is a technique that enable the localization of antigens at the ultrastructural level by labeling them with specific antibodies conjugated to (nano)gold-particles. The labeling is visualized as an electron-dense deposit in the site of the antigen-antibody reaction. IEM can be performed using the pre-embedding or post-embedding methods.

TEM Sample preparation

The workflow of samples processing for TEM involves several steps: primary fixation (performed in your lab), post-fixation, dehydration, infiltration and embedding in resin (performed in the core). Then ultramicrotomy provides thick sections (0.3 - 1 µm) stained with Toluidine blue suitable for light microscopy, and ultrathin (70 - 90 nm) sections stained with uranyl acetate or KMnOand lead citrate, ready for TEM imaging in the FEI Tecnai G2 Spirit BT transmission electron microscope.

Leica Ultracut UCT - ultramicrotome

The Leica Ultracut UCT Ultramicrotome is used for cutting thick and ultrathin resin sections, on either glass or diamond knifes, for TEM or SEM. Ultramicrotomy training is provided to users interested in obtaining their own thick and ultrathin sections.
