In the field of pre-clinical and clinical research, sample sourcing and the realistic quantities of tissues or rare samples available for biological analysis can be a major challenge for researchers. Comprehensive studies typically rely on both genomic expression and proteomic profiling readouts to gain for meaningful insights into biological processes, disease progression, or a drug’s therapeutic value, amongst other scientific questions. Well-plate homogenization is an important tool for high-throughput, rapid tissue disruption via bead-milling in well-plates for downstream genomic and proteomic analysis. In this application note, DNA integrity and the protein repertoire assessed using LC-MS/MS techniques for bottom-up proteomic analysis is reviewed after homogenization from rat brain, heart, and small intestine using the same instrument setting for full sample disruption.
