TissueFAXS CHROMA 
High-Speed Multispectral Tissue Cytometer

TissueFAXS CHROMA specializes in automated multispectral fluorescence whole slide scanning for up to 7 markers at a time made possible by an optimized filter set eliminating channel bleed through. This cost-effective high-speed slide scanner reaches its full potential when combined with single cell and contextual image analysis. This platform is a holistic solution for cellular phenotyping and in-depth tissue microenvironment characterization of IF processed tissue sections, TMAs, and cells on standard and oversized slides.

Technology

TissueFAXS CHROMA provides high-speed multispectral imaging and is made possible by a customized set of SpectraSplit filters. This specialized set of filters is optimized for a wide range of dyes with the appropriate excitation/emission spectra. This technology minimizes channel bleed-through passively and therefore represents a cost-effective alternative to the liquid crystal tuneable filter, which relies on lambda stacking and spectral unmixing of overlapping emission spectra. The acquisition of lambda stacks and spectral unmixing are time consuming and data-heavy processes. TissueFAXS CHROMA focuses on increasing sample throughput by minimizing multispectral scanning speeds without compromising spectral specificity and data integrity.

Adipocyte App: Measurement of Cellular Size of Adipocytes

The StrataQuest-based Adipocyte App was applied to this sample with the aim to automatically detect (i) the number, (ii) the size, and (iii) the diameter of adipocytes within the given fat tissue. The challenge of analyzing the adipocytes is that the nuclei cannot be detected properly since they are either usually washed away during the H&E staining process, or are not visible. Therefore, the App detects the adipocytes using the membranes of the cells.

(a) Shows fat tissue stained with hematoxylin & eosin (H&E). The App first detects the membranes of the adipocytes and minor membrane tears are automatically closed (b).  To detect the individual cells without nuclei, the App uses the detected membranes as a starting point and defines the cell by its distance from the membrane (c). Here the final result of cell detection is shown (d), cells are labeled in different colors for visualization purposes.

The App automatically eliminates adipocytes on the borders from the analysis which may influence the proper outcome of the analysis.

The results of the analysis are visualized in histograms and scattergrams. As shown in the scattergram below, the cells can be grouped according to their diameter (e) or (f) size.

By selecting a gate of interest within the scattergram and using the backward connection feature, the cells from the selected gate are viewed directly in the sample in their native tissue environment (g). In this case, cells with diameters of 120µm to 129µm are shown in red.

The gained measurements can be exported from StrataQuest in CSV and /or Excel format.
