This chapter outlines a method for sample preparation for bottom-up proteomics by LC-MSMS analysis of in vitro proliferated bovine primary skeletal muscle cells. The protocol describes the isolation of bovine primary skeletal muscle cells, extraction of proteins, proteolytic digestion of proteins, and desalting of the final peptide samples. The final peptide samples can be analyzed using various LC-MSMS systems after reconstitution in a suitable elution buffer.
