Faster Mass Spec: Same-Day Sample Prep Now a Reality

  • Reviewing the drawbacks of current sample preparation protocols
  • Defining technical parameters of new rapid digestion protocol
  • Comparing sequence coverage and total spectra on simple and complex protein samples
    using standard vs rapid digestion protocols
  • Presenting case studies using the rapid digestion kit

Summary

Preparation of protein samples for mass spec analysis is often the first of several bottlenecks in bottom-up proteomics workflow. Recent LC-MS/MS methods are as short as 10-minutes per run, and data analysis is more streamlined. However, the proteolysis step is often carried out overnight, extending mass spec analysis to 2 days. This bottleneck is challenging when preparing samples for drug metabolism (Pharmacokinetics) studies as well as complex protein samples (i.e., analysis of biomarkers). What if you could shorten digestion times to ~30 minutes, without denaturants or reductants/alkylating agents?
