Abstract
This is the overall workflow for LCMS top down proteomics of pancreas functional units from tissue sections using the MicroPOTS platform. The expected outcomes are proteoform identification and quantitation values from selected tissue functional units.
Tissue collection
The tissue sections were prepared and shipped from Vanderbilt-TMC following the protocol below:
