Advanced peptide mapping is a cornerstone of protein characterization in biopharmaceutical and research laboratories. Faster, more specific digestion methods reduce sample preparation time and improve data quality, enabling timely decision making in discovery, development, and quality control workflows.
This application note evaluates the performance of PeptideWorks™ Tryptic Protein Digestion Kits, comparing digestion speed, missed cleavages, and autolysis to leading solutions. It also demonstrates automation compatibility and day-to-day reproducibility using a robotic platform.
Proteins were denatured, reduced, and alkylated using guanidine hydrochloride, dithiothreitol, and iodoacetamide. Samples were desalted on Sep-Pak™ SEC cartridges, then digested with immobilized RapiZyme™ Trypsin at a 1:5 enzyme-to-protein ratio. Reactions ran at 37 °C, pH 7.5 for 30 minutes. Automation was performed on an Andrew+™ Pipetting Robot following the PeptideWorks protocol.
RapiZyme Trypsin enabled complete digestion in 30 minutes, compared to three hours for standard 1:20 protocols. Autolysis peaks decreased by 98% and missed cleavages by 78% relative to a leading competitor. Baseline chromatograms showed minimal noise, improving sensitivity for low-abundance peptides. Automated workflows delivered consistent peptide maps over three consecutive days, demonstrating robust reproducibility.
Integration of microfluidic digestion platforms and advanced enzymes may further reduce sample handling and analysis time. Machine-learning algorithms could optimize digestion parameters in real time. Expanded automation across multi-omic workflows will drive higher throughput and data consistency in both research and production settings.
PeptideWorks Tryptic Protein Digestion Kits deliver fast, reliable, and automatable peptide mapping with superior specificity. These kits streamline sample preparation, reduce analytical artifacts, and support consistent high-quality data generation for a wide range of proteomic applications.

Summary
Importance of the Topic
Advanced peptide mapping is a cornerstone of protein characterization in biopharmaceutical and research laboratories. Faster, more specific digestion methods reduce sample preparation time and improve data quality, enabling timely decision making in discovery, development, and quality control workflows.
Objectives and Overview of the Study
This application note evaluates the performance of PeptideWorks™ Tryptic Protein Digestion Kits, comparing digestion speed, missed cleavages, and autolysis to leading solutions. It also demonstrates automation compatibility and day-to-day reproducibility using a robotic platform.
Methodology and Instrumentation
Proteins were denatured, reduced, and alkylated using guanidine hydrochloride, dithiothreitol, and iodoacetamide. Samples were desalted on Sep-Pak™ SEC cartridges, then digested with immobilized RapiZyme™ Trypsin at a 1:5 enzyme-to-protein ratio. Reactions ran at 37 °C, pH 7.5 for 30 minutes. Automation was performed on an Andrew+™ Pipetting Robot following the PeptideWorks protocol.
Main Results and Discussion
RapiZyme Trypsin enabled complete digestion in 30 minutes, compared to three hours for standard 1:20 protocols. Autolysis peaks decreased by 98% and missed cleavages by 78% relative to a leading competitor. Baseline chromatograms showed minimal noise, improving sensitivity for low-abundance peptides. Automated workflows delivered consistent peptide maps over three consecutive days, demonstrating robust reproducibility.
Benefits and Practical Applications
- Rapid turnaround: full workflow in under 2.5 hours versus typical multi-hour protocols.
- Enhanced specificity: fewer missed cleavages and autolysis artifacts simplify data processing.
- Automation-ready: single-kit solution eliminates manual desalting steps and reagent sourcing complexity.
- Reproducibility: consistent results across runs and days support high-throughput and regulated environments.
