Rapid Detection of Necrosis in Breast Cancer with Desorption ElectroSpray Ionization Mass Spectrometry

This poster highlights how mass spectrometric analysis of ex vivo tissue slices from metastatic murine xenograft tumors from LM2-4 cell line with Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) allowed direct comparisons with histology images to determine the molecular profile of necrotic tissues. Showcasing that mass spectrometry is an ideal novel tool for rapid pathology and is highly complementary to current histology based methods widely used in characterization of cancer.
