Protocol for the Bottom-Up Proteomic Analysis of Mouse Spleen.

This protocol describes the comparative proteomic profiling of the spleen of wild type versus mouse, a model of dystrophinopathy. We detail sample preparation for bottom-up proteomic mass spectrometry experiments, including homogenization of tissue, protein concentration measurements, protein digestion, and removal of interfering chemicals. We then describe the steps for mass spectrometric analysis and bioinformatic evaluation. For complete details on the use and execution of this protocol, please refer to Dowling et al. (2020).
