Wide-Field NUANCE Microinjection Upright Microscope

The NUANCE multispectral imaging system is an enhancement to our wide-field microinjection upright to provides imaging of multiple molecular markers in tissue sections for both fluorescence and brightfield microscopy.

With Nuance, it is no longer necessary to stain many serially sectioned slides to monitor the expression of multiple markers. Nuance can visualize multiple nuclear, cytoplasmic and membrane markers, all in the same tissue section, and all with intact morphology. Cell-by-cell expression of various markers can easily be appreciated, and captured quantitatively, providing information similar to that achievable with flow cytometry, but with the advantage that the physical location of markers, cells, and tissue architectural elements are maintained.

Nuance can spectrally characterize all the spectral components in a sample, and use this information to automatically separate and quantitate each signal into its own channel—for both fluorescence and brightfield immunohistochemistry.
