MALDI imaging

Wednesday 23 December 2009

Histopathology proteomics adds the mass spectrometer to the arsenal of tools for the direct analysis of tissue biopsies and molecular diagnosis.

Typically called MALDI imaging, this technique takes mass spectral snapshots of intact tissue slices, revealing how proteins and peptides are spatially distributed within a given sample.
