Smile! Protein and peptide sample preparation automated

Application for high throughput proteomic sample preparation for LC-MS analysis

The challenge:

How do you improve reproducibility and hands on time savings in proteomics sample preparation for LC-MS analysis when you have already addressed the challenges of time, sample contamination and loss?

The solution:

Automate! Together, PreOmics® and Hamilton®* have developed a completely automated high throughput LC-MS sample preparation workflow, combining the Hamilton® liquid handling technology with the PreOmics® iST-PSI workflow. To meet the demands of high-throughput proteomics sample preparation, this fully automated, efficient and reproducible workflow helps decrease the processing time to about 4 hours and produces high quality samples for LC-MS analysis!

Apply! Simple, streamlined workflows

1. Adding samples
Samples should be liquid, homogenates or a soft pellet.
2. iST-PSI kit setup
Set up the iST-PSI consumables on the HamiltonMicrolab® VANTAGE Liquid Handling System®.
3. Sample preparation
Run pre-defined protocols in consultation with your automation specialist.
4. MS analysis
Analyze samples by LC-MS.
5. Data analysis
Process data to see improved peptide identities.


Figure 1: Inter-day reproducibility and comparison to manual processing.(A and B) 8 aliquots of manually prepared P. pastoris protein extracts(50 µg each) were processed on two different days, and 4 additional samples were digested with the manual procedure.(C and D) 8 samples of commercially available human plasma (each~70 µg; Sigma-Aldrich, P9523) were processed on day 1 and 2.
Figure 2: 96 sample run –  48 aliquots of manually extracted P. pastoris proteins were processed together with 48 samples of commercially available human plasma.
