Automated workflows

Automation is important for modern proteomics laboratories, where large number of samples are prepared daily.

Learn about the advantages of automated sample prep workflows and explore how Evosep One users have standardized their sample prep workflows with automation.

Automation eliminates variations and increases lab efficiency

With an increased sample throughput on the Evosep One, it is possible to prioritize a high number of technical and biological replicates in a dataset providing excellent strength in the downstream bioinformatic analysis.

Automation can remove human variation and increase lab efficiency, bottlenecks that most labs are constantly working to remove.

There are already several elegant solutions available when it comes to setting up an automated sample preparation workflow and it is now also possible to perform automated sample loading of Evotips, which can be extended to integrate upfront digestion workflows.

 

AN AUTOMATED OPENTRONS LOADING PROTOCOL FOR SIMPLIFIED SAMPLE LOADING OF EVOTIP PURE

As a step towards end-to-end workflows, we have developed a simple and automation friendly protocol for sample loading on Evotips, which makes use of a layered sandwich approach with defined airgaps between the layers.

This sandwich is pushed through the Evotip with the OT-2 pipette for 100 seconds leaving the Evotip ready for injection on the Evosep One. The automated sample loading protocol relies on a defined sample volume of 20 µl and solvent A volumes of 15 µl and 150 µl respectively to keep the sandwich intact through loading.

The protocol has been converted into an easy-to-use HTML form, that generates a complete python script for use in the Opentrons app, allowing the user to load from 8 to 288 Evotips in a single run.

SEMI-AUTOMATED SAMPLE LOADING USING THE AGILENT ASSAYMAP BRAVO

The Agilent AssayMAP Bravo supports efficient and reproducible loading of samples onto Evotips with a median peak area CV of 6.3% and 8.5% across a box of Evotips when using a single column and a full head respectively.

This workflow can easily be combined with a range of already existing workflows on the AssayMAP Bravo. Furthermore, the Evosep One combined with the Agilent 6495C represents a stable analytical platform for targeted applications.

AUTOMATED WORKFLOWS FOR DIGESTION AND PHOSPHOENRICHMENT USING THE KINGFISHER FLEX

At the University of Copenhagen the Olsen group has developed streamlined fully automated workflows for sample preparation in collaboration with Resyn Biosciences.

Protein digestion and phospho-enrichment is fully automated for up to 96 samples in parallel with the Kingfisher Flex robot from Thermo Scientific. It takes advantage of the fast scanning speed on the Orbitrap Exploris 480 MS – the ideal combination with short gradients on the Evosep One.

Automated Workflow for Immunoprecipitation using the Agilent Bravo AssayMAP liquid handling robot

This publication from University of Oxford led by Adan Pinto-Fernandez, describes a new methodology named ABPP-HT (high-throughput-compatible activity-based protein profiling).

It implements a semi-automated proteomic sample preparation workflow on the Agilent Bravo AssayMAP robot that increases the throughput capabilities of the classical ABPP workflow approximately ten times while preserving its enzyme profiling characteristics.

HIGH-THROUGHPUT HCP ANALYSIS FOR INDUSTRIAL ENZYME MANUFACTURING using Opentron

Novozymes produces recombinant enzymes and microbial solutions for a plethora of bio-based industries.

To meet regulatory demands, they have developed a highly efficient and streamlined HCP workflow, which translate raw samples to data in less than 24 hours, with less than 2 hours of hands-on time.
With a focus on throughput, they have standardized on the Evosep One 200 samples per day method, combined with the Bruker timsTOF Pro and automated data processing by GeneData.

This platform allows them to robustly identify 700-1200 intra-cellular microbial proteins in a sample with average CVs of less than 5% based on five replicate injections.
