Andrew+ Pipetting Robot for PeptideWorks (ORDERING INFORMATION)

Significance of the Topic

Automated sample preparation is critical for reliable peptide mapping of therapeutic proteins. Variability in manual workflows can lead to inconsistent digestion, unwanted modifications, or enzyme autolysis. Integrating a dedicated pipetting robot with validated reagent kits enhances reproducibility and streamlines routine analyses in biopharmaceutical quality control.

Objectives and Overview of the Article

This document presents the integration of the Andrew+ pipetting robot with PeptideWorks tryptic digestion kits and OneLab cloud protocols. It details the automated workflow for peptide mapping, outlines available kit configurations, and describes system components and options to support high throughput sample processing.

Methodology and Instrumentation Used

The automated workflow comprises two core protocols in the OneLab cloud library:

• Protocol A for protein denaturation, reduction, and alkylation followed by desalting using SEC cartridges.
• Protocol B for enzymatic digestion at 37 degrees Celsius with RapiZyme trypsin and quenching with formic acid.

Instrumentation and consumables include:

• Andrew+ pipetting robot with single and multichannel pipette adaptors, waste base, and gripper module.
• OneLab software for protocol execution and optional concentration normalization.
• PeptideWorks starter and refill kits for four or twenty four sample batches.
• Sep Pak SEC desalting cartridges and ACQUITY peptide CSH C18 columns.
• Pipette bundles, consumable dominos for deck layout, plates, tubes, and tip racks.

Key Findings and Discussion

The combined system processes up to twenty four samples in under three hours, offering rapid turnaround for routine peptide mapping. Predefined protocols reduce method development time and ensure consistency across batches. The compact robot footprint allows placement on a standard laboratory bench or within a biosafety hood.

Benefits and Practical Applications of the Method

The automated workflow delivers:

• Improved accuracy and reproducibility of digestion and cleanup steps.
• Streamlined method validation and compliance support.
• Flexible scaling from four to twenty four samples without protocol modification.
• Reduced manual handling and risk of sample cross contamination.

These advantages support quality control and stability studies for biologics in academic and industrial laboratories.

Future Trends and Potential Applications

Further developments may include expanded OneLab protocol libraries for glyco mapping, non tryptic digestions, and post translational modification analysis. Integration with laboratory information management systems and real time data analytics could enhance process control. Miniaturization and higher throughput platforms will continue to meet growing demands in biopharmaceutical research and manufacturing.

Conclusion

The Andrew+ pipetting robot coupled with PeptideWorks kits and cloud based protocols offers a robust solution for automated peptide mapping. By delivering rapid, high fidelity sample preparation, the system addresses key challenges in therapeutic protein analysis and supports efficient laboratory workflows.
