Imaging Mass Cytometry (IMC) is an approach for the targeted and epitope-specific multiparameter analysis of tissue sections (Scheme). In contrast to conventional immunohistochemistry or immunofluorescence, this technology allows for the simultaneous detection of >35 specific markers on the tissue by using metal-isotopes and their different masses as analytes. Tissue sections are labeled with epitope-specific, metal isotope conjugated antibodies and the tissue is ablated in 1x1 µm spots by a laser. The ablated material is carried into the mass cytometer, and the metal ion content of each pixel is analyzed by time-of-flight mass spectrometry. The signals are then plotted as a multiparameter image that can be analyzed by any imaging software. For more information about this new technology contact the core facility.

Measurement of tissue samples

IMC is offered as service (staff-operated) or independent usage with assistance. Measurement of tissue sections can be requested via OpenIRIS ('Services' - 'Imaging Mass Cytometry - Sample Acquisition') with a date/deadline and will then be coordinated by the core facility. Longer measurements usually run overnight or over the weekend. Please request measurements as early as possible.

For all new projects, the new Hyperion XTi (Blanche) will be used.

Please request a project meeting at least 6 weeks before start of a new project to get access.
A sample acquisition template (download) has to be uploaded when submitting the request and a description of the slide (download example) has to be provided.
