Sample Preparation:

Sampleprep ID:	SP001940
Sampleprep Summary:	As stated in the msiPL paper: For the Prostate tissue: Briefly, 12 µm thickness prostate sample diagnosed with a Gleason score of (3+4)=7 were mounted on a microscopy glass slide and coated with CHCA (5 mg/mL in 70/30 methanol/water with 0.1% trifluoroacetic acid V/V) using an automated sprayer (TM-Sprayer, HTX Imaging, Carrboro, NC). The analysis of the samples was performed on a 9.4 Tesla SolariX XR FT ICR mass spectrometer (Bruker Daltonics, Billerica, MA) using the MALDI source in positive ion mode in the mass range between 250-1000 m/z, with a spatial resolution of 120 µm. For the PDX GBM mouse brain dataset: The intracranial tumor belonging to a PDX model of GBM12 (PDX National Resource, Mayo Clinic), was analyzed by MALDI FT ICR MSI using a 9.4 Tesla SolariX mass spectrometer (Bruker Daltonics, Billerica, MA), using continuous accumulation of selected ions in the mass range between 380-620 m/z. The indium tin oxide (ITO)-coated slide with 12 µm thickness tissue sections , was coated with DHB (160 mg/mL in a 70/30 v/v solution of methanol/0.2% TFA), according to Randall et al2. The 3D MSI dataset was collected from 4 tissue sections with an inter-slice distance of 160 µm. Internal online calibration was performed using heme m/z 616.1776 during data acquisition.
