3D DESI mass spectrometry imaging of 52 serial sections from a human colorectal adenocarcinoma

Fifty-two serial sections from a single human adenocarcinama are made available in this dataset. Four neighbouring sections were placed on a single slide and analysed together. The tissue sections were analysed by desorption electrospray ionisation mass spectrometry imaging (DESI-MSI) according to the procedure outlined in the associated publications. The data files are made available in centroid- and profile-mode imzML format. Additionally, H&E-stained optical images are included.
