| Outline of Final Research Achievements |
Protein aggregation causes severe damages to cell and tissue functions. In the present study, we developed a new proteomics sample preparation method that is applicable to minute amounts of aggregates including those isolated from cultured cell lines with laser microdissection systems. This method, which we call BOPs, combines two advantages of current techniques, (1) unbiased binding of reversed-phase polymeric microbeads to any type of protein and (2) enhanced trypsin digestion efficiency in CH3CN-aqueous solvent systems, into a single-tube workflow. BOPs can readily be adapted to a wide range of diluted or denaturant-contaminated samples with high sensitivity, reproducibility, and reliability. The availability of the present BOPs make it especially attractive for next-stage proteomics of rare and limited aggregates.
