Smile! Protein and peptide sample preparation automated

Applications for Agilent Bravo

The challenge:

How do you bring further standardization, reproducibility and hands on time savings to proteomics sample preparation for  LC-MS analysis when you have already successfully addressed  the many challenges of time, sample contamination, sample loss and reproducibility?

The solution:

In conjunction with Agilent, PreOmics®' kits are suitable for use on the Agilent Bravo platform. Meeting the demands of reproducible, robust and sensitive proteomics sample preparation for LC-MS analysis, these applications allow research labs to partially automate proteomics processing, decreasing the hands on time.

Apply! Simple, streamlined workflows

1. Adding samples
Samples should be liquid, homogenates or a soft pellet.
2. iST kit setup
Add the appropriate iST kit components to Agilent Bravo.
3. Sample preparation
Protocols need to be programmed by an in-house specialist.
4. MS analysis
Inject samples into your LC-MS system.
5. Data analysis
Process your data to see improved peptide identities.

The partially automated Agilent Bravo requires off-board centrifugation. The figures above show data generated on the Agilent Bravo in a partially-automated protocol, using 1 µL plasma with analysis on a Thermo Q-Exactive HF Orbitrap.
